get S/C installed & get used to it  ?

Big Brake Kit (BBK)

 

 

then, after you get used to it...

Blackbear tune

CAI

smaller s/c pulley (guessing you have a 3.4...go 3.1)

 

then when you want to get crazy:

LT headers (& maybe a resonator - to quiet it down a hair)

plug wires & 1 step colder plugs

custom driveshaft

even smaller s/c pulley (& new belt)

throttle body

retune

injectors/fuel system

cam/lifters (DOD delete)

pistons

meth

torque converter

etc...

 

LOL

Dude... baby steps. I'm into Corvettes and 1 out a 100 sold will be crashed coming out of the dealer....  LOL

Recently picked up a '18 6.2 silverado centennial edition.  Added a borla s-type catback system.  Installing a Magnuson TVS1900 Supercharger.  Had thought about throwing some long tube headers on it a

Beautiful truck. Always liked that 100 year anniversary truck color. Good luck with your build. I am all about speed and a charged 6.2L will fly.   Just curious, why didn't you get the TVS23

What is that you have mounted on the firewall? Did you add that? I am extremely unhappy with my tvs 1900 in my 2014 sierra, I can't drive it as it won't idle properly. They are not being helpful at SLP and I don't know who to turn to. I am at the point of unistalling it until I find someone who can help me.

@wilshire37

thats an oil catch can on the firewall.

 

 

sucks about SLP... what did they say when you talked to their support?

as it sounds like could be tune type issue.

also double check all connections that were removed during install.  maybe something didnt seat or got pinched.

 

how many miles are on your '14?

any maintenance items need to be looked at?   i.e.:  plugs, plug wires (maybe loose) , fuel filter, etc

 

check engine light?   might be worth getting it scanned for codes.

 

 

also curious.... what is your idle rpm?     mine used to be 500 & at times it would be rough just sitting there, but fine driving.

i got a BBP tune & had them bump it to 600.   fixed my issue

 

any local tuners close to you?  might be worth stopping by.

My idle on a cold start is normal, then as it warms up it drops to between 350 and 500 rpm. It then starts popping through intake and out the tailpipe like a bad maf. So I put a factory replacement in(AC Delco) and nothing changed. So I unplugged the maf and it idles perfectly until you touch the gas then dies and the CEL is present for the unplugged maf codes. I got it on the highway and it ran pretty good but under a certain speed decelerating it is awful. The truck has only 27462 miles on it. The only upgrades were MSD plug wires, fresh plugs, AFE coldair intake, gibson shorty headers and a magna-flo cat back exhaust. I also use a range technologies plug-in the OBD to keep it in V-8 mode. The truck is meticulously maintained since new. I did double check everything and it all seems tight. Sometimes it will stall and throw codes for the top o2 sensors having low voltage which makes sense because the idle will bottom out and stall. SLP support told me to email the tune guys and ask for a new tune and describe whats happening but no one is getting back to me. I will look into a local tuner, thanks for the reply and I will update if I figure it out.

That’s weird what plugs are you running. I have the LT4 plugs. Also I would get a professional tune def. it could be the idle parameters in the tune itself. Idk just throwing things out there.

shouldnt need range device now.   SLP should tune out the V4 mode

doubt that would mess things up, but might try removing 1 extra variable.

 

& 350 rpm is too low for idle.

really shouldnt go below 500

 

550 to 600 is better

Don’t use factory plugs you need a little hotter burning plug then factory. Also those pre loaded tunes are enough to get you going. Your leaving a lot of HP on the table. The tuner bumped my idle up to like 600 or 650. Plus are tour fans running all the time?

I am waiting on SLPTUNE to get back to me. I am going to contact black bear and see if they can help me out if slp won't. Anyone know if I can use my sct tuner with them?

gat0r is correct we use EFILive, so the AutoCal or the V2 would be the way we would tune your vehicle with the supercharger,  and it would not be compatible with the SCT tuner.

      87 down as low as $5.14 here... winning!

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.
