2008 RCSB traction control ?s

a guy at work has a 2008 chevy truck with the 4.8 that i've pestering him until he finally got a cam, stall and some longtubes. i tried to pick the stuff for him and get him a tr224 cam and a nice converter and headers and have Nelson tune it, but he wanted it all to be done by the dealer and had them put in a gm hotcam and whatever stall and longtubes they have i guess and they had some guy remote tune it from another dealership.

it sounds great.... BUT it still has no ass off the line and it takes till almost 3rd gear until it really starts to pull, i assumed it was traction control or TM we looked all over his truck and never found a traction control button to turn it off. i figured they could turn it off in the tune or down or something so it wasnt such a slug off the line.

he went and talked with them and they told him "you cant turn off the traction control without loosing abs" and that he had to pull a fuse to get it to work, so they are making him a little switch that pretty much kills the power to the traction control so his truck will have some guts when he punchs it.

does this sound legit? i know plenty of people have these trucks running great times and whatever and i cant really believe this is how its done, i think the dealership is just stupid.

can anyone confirm this mess?

RS/SS 4.8

Dealerships are stoopid. Mines got 4.8 rcsb, tsp 220, 3200 stall, 32 inch tires and 3.23s and ive been through several rear tires.

lol i tried to tell him to get a tr224 cam and he showed the dealership that and they go "wow thats a racing cam!" lol i told him he wasnt getting his moneys worth there, but some people just are scared of working on engines.

imma show him what a boosted 6.0 will do soon though that may change his mind lol

yeah his truck doesnt have one though, it would if it was a different model from what i've seen on the net but his is pretty much the base model with power locks and windows, and its just a blank spot where the traction control would be.

Lift is .525/.525 so it should have down low power. Thats not super big but should help it out.

Pretty sure all 2010 4.8s have vvt, did they convert from the VVT to non VVT when they did the hot cam? I have a pretty similar setup in my 4.8 and my truck acts the same exact way. NOTHING down low then when it starts rolling the power comes on. I starting to think the 219/228 split is not a good duration for that engine, its possible if they kept the vvt they installed the wrong core also. I am actually in the process of swapping to a smaller duration cam. Below are some desktop dyno numbers. I know its not gospel but it gives a good idea of how the engine will react. BTW I only have the older version so had to use a gen1 block and change the bore/stroke, valve sizes, and may even be wrong on the intake cfm but use it for a general idea.

This one is 4.8 with a Hot cam and according to my Butt dyno I would almost confirm these numbers are pretty close.

This the exact same setup but with the valve events from my new cams card and you can see a dramatic increase. I will have it in by tomorrow and shipping the pcm to NP for a reflash.. I let you know how the butt dyno feels after.

The big problem is that they put in a hot cam. Ask 97% of the people who have had them...sound great, run like crap.

Sounds like a dragster runs like a aveo..... Well maybe not that bad.. Sux when you pull out of somewhere and someone gives you the universal hand motion for a burn out and you have to act responsible because you look like tool when the engine makes tons of noise with no smoke. My "hot cam" will most likely be on the beer fridge by this time tomorrow next to the stocker. BTW I though all 2010 4.8 and 6.2 had VVT and the 5.3 had DOD only.

My 2011 4.8 is VVT!

i was wrong on the year its a 2008 and it doesn't have VVT, anyways i pulled the #9 fuse and it didn't do shit really other then put the ABS and parking brake lights on. form a dead stop and nailing it it takes off the same as if you give it 50% throttle and has no guts until about 45 or so.

i drove it today and it seems the converter is around a 2200-2400 ish stall,

any suggestions other then a different cam/tuner?

34-3600 stall. No joke a new cam would be a night and day difference in there.

well we finally found out what stall he had, they gave him a trailblazer unit that's like a 2600 stall, also were all working in florida and we spanked his ass with our rental nissan murano, haha.

anyways the next day i helped him hook up with nelson and we have a tune coming that will hopefully fix a bunch of his problems!

A tune isn't going to fix a mechanical issue. Did you not just say the problem was the stall?

i dont think there is anything mechanically wrong with the truck it seems to move out pretty well from 45-50mph on up but 0-60 is complete shit, i just that the dealership doesn't know how to tune that well.

Probably just tuned it so it will idle and drive. GM has "tunes" they can upload through the Tech 2 for all the GMPP cams.

I think the mechanical problem hes speaking of is the lack of stall speed. Like stated previously in this thread that cam needs about a 3400-3600 stall. So yeah with a 2600 stall there is a "mechanical" problem.
