I have received numerous PMs asking about my tune, so many in different threads, I don't believe I could find them all, so I thought I would just initiate a seperate thread to address it. This may be

I just had Black Bear tune done and wow my truck at full throttle shifts into 4th at 100 mph. Transmission shifts so much better. Throttle response is fantastic. Best tune I have ever had done.

Karnut. Seriously I cant really just put a number on it because of the amount of responce you get in your throttle!!! If you put it on a dyno the peak numbers will or could have up to 25-30 gains but

Hello everybody, I'm new here, but soon to have plenty of questions.  First off, however: my 2016 6L80 tranny just turned 70,000 km's (43,000 miles) - I have every intention of putting a Sonnax Zip Kit to boost shift pressure etc.  Keeping in mind I run my truck offroad on 32.5"'s regularly, and I'd like it to survive as long as possible, including future 35's.

 

My powertrain warranty is up in two years, which will likely mean about 100,000kms/60,000 miles; I intend to install the sonnax kit in parallel with an i3 tuner (hard shift setting) and 4.56 gears, which should all help the tranny in the long run.

 

In my experience...learned mostly the hard way...such kits are only beneficial if used while the transmission is healthy.  The question is: is 100,000km too late to put a zip kit in, or is it worth the risk to have it put in ASAP?

 

Short term risk-long term reward considerations here.

hand held canned tunes wont make much power... because they cant touch the PE tables otherwise the FEDs will be on their ass, shutting them down for emmissions violations!  they may add some timing,  disable TQMnmnt, disable cyclinder deactivation, tighten the line pressure in the trans, thats about it.

the power is in the PE table

I will say this after you receive a Tune run a Data Log after running the New Tune for 200 miles. Then have them check it mainly in the area of RPM Idle and Transmission Shifting/Performance.

I have noticed with the 2014 5.3 L83 and my nephews 2017 5.3 L83 after tuning the need to bump the Idle RPM's, very small adjustments. The 6L80 6speed Trans can produce nice results when tuned but it may take the extra Data Log to update the Tune for optimal performance and longevity.

I'm editing my original post.

 

2019 LD old body is the same access for tuning as 2018.  4 credits through HP Tuners, same E92A ECM.  My tuner got in no issue.

I've had my 2014 6.2L for a few years now and I'm planning a tune.  The only reservation I have is, on the last page of my owner's manual, someone stuck an HPTuners sticker on it AND I've hit 130mph with no problem before...If someone removed the speed limiter, what are the chances my ECM would be locked and I couldn't tune with Blackbear? Can you just remove a speed limiter with HP Tuner?

So just buy HPTuners then :)  - shouldn't be a problem though - HPTuners doesn't lock anyone out of doing anything. Worst case scenario the previous tuner locked the tune and then Justin just has to dig into his own tune repository for a stock file that would match your truck.

i would focus on the trans tune first, remove the lock up converter settings,  lock up should only occur in 5th and 6th gear, less wear and tear on the weak clutch.  reduce TM by 18-25%.  get your trans temps down to 120-130F street driving.  do the Fast trans relearn after any updates..

this should improve longevity up to 180,000 miles

 

there are a dozen more adjustments that need to be made, but start with the basics before going advanced

My first custom tune was a Diablew tune on my 2013 Black Diamond Avalanche with a used diablo tuner off flea bay; cost me about $350 total and it was well worth it; had greatly improved drivability that was most apparent when I took off the tune to drive it in for the trade - I couldn't believe how bad the stock slurped. The trade is a 2018 Suburban LT 4x4 5.3, and though I want to try a BB tune, they have crept up to around $700 these days. I'm sure they are great, but there is only so much a tune can do, and 7 hundy is most of what my new Corsa cost (it alone is fantastic). Instead, I opted for the diablosport tuner to again let Lew tune after I got my new exhaust installed, and flea bay has tuners. Much to my chagrin, I picked up a refurb factory diablosport for cheap, and put on the "Jammer CAI" tune that was on the tuner. Apparently, its a 91 tune specifically for that brand CAI, but since I have a Airaid Jr and a new Corsa sport, I figured an increased airflow tune would apply until I got a few tanks of 93 through the truck. I added 11% throttle increase plus AFM off to that tune and kept everything else the same. Its sweet. I'm not sure if I got lucky or what, but this thing breaks loose. Could be the Corsa effect (which is, BTW, the best exhaust I have ever owned), but man I am one happy mofo right now...

 

Update. Lost about 3mpg with that no afm 91 tune. Went to 93 diablo tune with afm, and got it all back, plus it seems to run a little bit better...

I'd like to get my new Jasper 6speed transmission in my 2016 Silverado tuned. Anyone have any recommendations for someone in the Kentucky or Ohio area?

I bought the Flashpaq F5 and did some tuning myself - 91 Octane tune, AFM delete, tire size reset.
It does allow a tune for shift points.
To be fair, that's not something I'm interested in, but it can be done.
Oh, I did change the the speed tor the CC lock-up, so that can be done, as well.

Looks like a pretty neat device, but to be honest I wouldn't have a clue how to use it or how to even program my transmission.

 

I'd love to find a local or semi-local guy that has done this and know what they are doing. Haha.

 

Otherwise I'm making the 12+ hour drive up to see @CamGTP :D 😉

Dkgoodrich.com in Frankfort KY. He does HP tuners and really knows his stuff.

      2014 silverado wt radio and hmi upgraded to i06
       
      This truck never had a back up camera. Upgraded from i04 to i06 via hmi. installed proper back up camera in tailgate, plugged in to RC port. BUT
       
      The error from the ecu indicate that the line is open. So, my thought is that the wiring is not there. I was told if the grey and yellow wire are there its there, but even if it is from the back to front, it might not be across the front to the unit.  I was temped to use a harness that would plug into that plug and add a simple rca add.
       
      So I have a black screen with  directional lines that work. Then it goes black and days service required.
       
      I took it to the dealer, they want 1200 to do it all. uh, no. I need a simple solution. help guys. please.

      I have 2014 Silverado and went to the gas station one morning and out of nowhere started smelling gas inside of the truck. Long story short, went to look underneath truck and had a 3x3 ft size puddle of fuel underneath truck on ground. Looked to see where it was coming from and looks like it’s coming from back side of motor. Can anyone help or recommend any action to take from this?

      Hi
      I'm new in this group, I hope you guys could help me out.
      I'm driving a GMC SIERRA 2014 ALL TERRAIN MODEL and I been trying replace my blower motor resistor, but the problem is that... I don't know where is located, according Google, amazon and o'reilly I bought the correct one. Every body is saying that is normally next to the blower in the passenger side, but I couldn't find it. I'm leaving photos to show you guys how it looks right where the blower is..
       
      Thanks

      So ive been seeing the conversion on 08-13 Sierras , and very popular on Silverados even the 14-16 conversions. On feb 1 some jack ass cut me off and hit my front bumper and fender , lucky for him i was already looking into doing a 2018 denali headlight conversion with the gen5 wiring harness and 2015 HD front bumper with 2500 all terrain grille To keep the theme going. As I researched could not find anything on the 2014-2018 sierras being converted to HD , all the guys i saw on IG with them had shops or buddys do them. Some guys welded either the 1500 or 2500 brackets lower ,enlogated the holes lower, redrilled , some had no gap -some liked oem gap between the grille/fenders. I did find two guys I kept intouch with they were a lot of help. One sent me pictures on how to re-drill the stock bumper brackets lower and cut some parts off it to clear the bumper , the other told me 1/2 above the existing holes . I took it upon myself to source a complete front bumper from ebay with everything $750 with shipping all i have to do is paint it , found a all terrain grille on ebay for $300 , had to buy the 2500 bumper guides and 2500 bumper fillers no luck on hood yet.while the parts arrived i bought the 2018 denali lights from fankie on here and the harness from gen5 easy bolt on by the way. When all the parts arrived i grabbed my grinder and drill .
       
      To start i took the 15torque head screws and 7mm from the sides of the wheel wells , took the 12 plastic clips from the upper cover , removed the 4 top 10mm bolts ,pulled off the bumper filler pieces between the grille and bumper , exposing the 10mm 4 bottom grille bolts , then removed the grille. Gaining access to the 4 18mm bolts that hold the bumper on the brackets, i loosened but did not remove till i went under the front bumper and removed the 2 outter 15mm bolts that hold the bottom of the bumper , i loosened the inner 15mm bolts but did not remove , once that was done i removed all 18mm bolts  holding the bumper and took it off . Once off the stock 1500 bumper brackets have 3 15mm bolts in a triangle pattern, i removed all 6 and removed the tow hooks , the tow hooks will be eliminated from this . Once i had the brackets off i measured 1/2 inch above each hole . Now this is important if you want oem gap like myself i drilled a hole slightly bigger than the bolt going threw at the center of that 1/2 mark . If you dont want gap id suggest drilling under the 1/2 mark and possibly enlongating that hole down wards for adjustment. By drilling the hole a 1/2 inch higher it drops the bracket to clear the 2500 grille . In addition to redrilling the bracket you have to cut an L shape on top right next to the top bolt that the bracket has , i actually cut the bottom of the bracket and eliminated the bottom slot for the second 18mm hole because i was having issues lining up , ended up not being the problem , i found that out of the 6 15mm bracket bolts you only use 4 the top and inside 15mm the outter 15mm that completes the triangle actually hits the hd front bumper and it sags in the back ,so removing levels the bumper flush , i tried grinding the head down and still no luck removing was the fix. With the bumper off , you want to remove the 1500 bumper guides 3(7mm) bolts rachet wrench works best and socket aswell , install the 2500 bumper guides with same bolts same place these support and clip on to the new 2500 bumper filler pieces under headlights which youll have to buy . They clip and slide right on , the two bottom outter 10mm bolts that held the old grille will hold these in place and the other two 10mm in the middle from the old grille will be eliminated. See pictures.To finish securing the bumper filler and guides you have to screw the  7mm and 15 torque screws by fender trim , you will either have to buy the 2500 or 18 fender trim pieces or just trim yours roughly enough to bolt on the remark to trim perfectly and level like i did cant even tell .So Once the guides and fillers are installed grab the redrilled bumper bracket to your liking in gap, make sure its clearanced with the L shape you can rebolt bolt to frame leaving the outter 15mm off at that point you can lay the new bumper on the brackets rebolt the top 18mm bolts the bottoms wont line up -i eliminated by grinding off ,see pic -you can reconnect the lower 15mm outter brace and tighten , youll find out that it bolts right up and if you drilled at 1/2 center like me you keep that stock oem gap maybe a bit tighter gap actually but it looks good , you can then install the grille by pushing the clips in and only bolting on the the top 4 10mm bolts once done youll find that the gap is nearly perfect if you drilled at center of the 1/2 mark , some drill under the 1/2 mark to get less gap and some enlongate the hole lower towards the original hole  to adjust and have no gap , but i see that as rubbing issues with paint.
       
      sorry for rambling on on the install , i will try to post all my pictures size will be limited and ill go back to proof read fix anything that i missed. Let me know waht you guys think or if you need help

      Looking for suggestions on front coilovers for 2014 SIlverado 4x4, I currently have a 3" motofab level kit installed including aftermarket Motofab UCA (Which I am not happy with and will be swapping out)  Nevertheless I would like to maintain the 3" lift but go away from the spacer to a coilover kit without breaking the bank.  I have been looking at the following and interested in feedback outside of going to a full blown 4" lift which I'm trying to stay away from but not opposed too either.  Also to mention this is my daily driver so more on road than off road use.
       
      Bilstein 6112- won't get me to 3" only 2.75 at highest setting (maybe)
      Eibach Pro-truck Coilovers 1.75-4" $850 which I'm leaning towards due to price but not familiar with the coilovers I know Eiback makes a good spring which is used on several other brands including FOX
      Zone Coilovers 0-3" around $2K to purchase  (Ouch)
      Icon 1-3" Coilovers about $1720
       
      these are just a few I have researched but open to thoughts and suggestions and looking forward to the feedback, I'd like to stay under a thousand if possible.
