On Friday afternoon I took a ride down to a friends shop (www.raceprovenmotorsports.net) to get my car tuned. The shop is mainly an LSX based shop but they do work on Cobalts when they are not building 8 second Z06's. The dyno is a dynojet and all runs were made using SAE and a smoothness of 5.

Bone stock the car put down 243whp and 234wtq. It was pulling timing for knock and running in the 15s for air/fuel around peak torque. Simply adding low end fuel bumped the torque up to 252wtq and did away with the knock. I'm kinda shocked about how much timing was being pulled on a stock car. Alright, enough playing around.

Tuned it put down 291whp and 311wtq. Maxing the DAL table would only net 20.1psi...not that im complaining :lol: I'm assuming this is because the car has no work done to it where others that are getting 22psi do?

This is by far the best bang for the buck since Nitrous. The car is an absolute blast to drive now. Before it wouldn't spin the tires in first gear...now it's spinning in 2nd gear :twothumbs

close to my numbers 293whp 312wtq. good job.

where do you find a hp tuner at? looked briefly through the vendors to no avail

now for 1/4 mile times! i say 13.1s all day

High 12's with DR's??

Nice very impressive for just a tune! :D

now for 1/4 mile times! i say 13.1s all dayDon't put me on a pedestal just incase I don't run the number :lol: I feel it has a 107-108+trap speed...i just don't know where that will fall in the 1/4.

i believe u can do it lol

Glad you are happy. We need more mods so we can put it back on the dyno.

very nice man.

well this answers my question of whether or not Race Proven can tune Cobalts.

rock on man :twothumbs

whoa!!! i just remembered something, haha. a friend of mine just had his LS1 GTO dyno tuned there a couple months ago, he showed me a pic & vid of his car on the dyno. did they move the dyno? i thought they only did RWD. haha if you have a pic of your car on the dyno, that would be great.

The dyno is still in the same place. I think the whole "we only do rwd" thing is to avoid the Hondas coming to the shop. They laughed about how quiet the car is. They could still hold a conversation while it was on the dyno :lol:

:lol: i fail.... can't see pics at work :facepalm: i'm assuming you were able to just drive up on it? i might have to hit them up about getting my car dyno'd, i haven't dyno'd on a DynoJet since it was stock last fall. and i dont blame them for wanting to keep the ricers away, i know up North DE there are tons of them!

Out of curiosity, how much did it cost to get this done? Ive been debating on what I want to do for my tune and these guys aren't to far away.

I will charge 500 including dyno time.

Drew you jinxed me.The best I could muster out of it tonight was a 13.4 at 107.4. I'm heading back down to the track once the weather cools down and maybe the low 13's will happen.

lol u got it next time for sure. weight reduction...i got my car down to 2820lbs w/o me on 3/4 of a tank. go with like a 1/4 tank and u can make it around 2750 w/o u.
