I mean they already get shitty fuel mileage emoji2375.png

That they do.  When i first got the truck drove it from va to ny saw best 15 mpg on 87.  I run e85 and get a best of 13.  Thats all highway, city mpg sux.  Im wondering if 93 would be better.  Shitty thing is its 2.69gal vs 1.49 for e85

So heres my update on the gears . Just dropped the 5th wheel upstate. 120miles 1 way all good. She did good, only struggle a little on the 4 mile 5% grade climb. Had to drop to 50mph so i wasnt screaming over 4k rpms. Got 5mpg on the way up towing 15k lbs. On the way home an hr into the drive got a p0700 and a p0741. Cleared the code. A hr and half later i get locked into 4th gear no cel. Get home hook up scanner and p0741 is in the history. This has been happening for 2 yrs. Thought it was my tune, put stock tcm tune in and changed fluids and filter 3 months ago. 15 2500 6.0 62k miles. So now gonna get trans looked at, been dealing with this issue for 2 yrs and finally got a code.

don’t wanna be a jerk but i will say this.  i love working on and modifying vehicles, but i don’t mess with new stuff.  i have a 72 k10 with a 396 and a 65 goat, always messing with them.  my 2016 2500hd?  bone stock.  no tune, tiny 245/75r17 tires, nothing.

 

i would love to drive a lifted truck with bigger tires, a tune, maybe even a supercharger.  but i ain’t messing with my 2016, because i rely on it and don’t want any problems.

 

if you wanna play, i think there is a lot to be said for finding an older second rig to mod and keep your newer truck stock.  just how i handle things myself.

 

good luck, OP.  hope it works out.

My issue started out prior to me modding. The new gears were to help to my 5th wheel. These trucks should have came with 4:88

      AUX switch install

      By SwitchBladeSierra · Posted

      Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.

      By jgaudet99 · Posted

      Well I ordered the Autel ts508, and it won't work on my truck I tried all the 2023 and everything it just says vehicle not supported lol   I'm able to send this unit back, so I'm going to do that, then I'll just stop into a some tire shops and if none of them are able to do it, I guess ill have to spend a bunch of money to get a good scanner..... Thanks GM lol

      Needing this part.

      Don't need the air tube but that's how everyone sells them. Most places won't remove that one piece and sell it alone. No money to be made. Hoping someone swapped theirs out for a CAI and no longer wants it. Not asking anyone to give it away. Offering to buy it but I don't need the tube. It's held on by a hex head screw and nut. Been all over eBay.
