Sorry to hear about your car, I didn't see if it had been tuned via LS1edit yet ?

When I first got my car back from the speed shop (baby cam, no heads) my car ran like sh*t, it surged like hell and would stall at every light - even when I was going 15mph and hit the brakes. Anyway I took it back the next day and expressed my concerns, they discovered something overlooked on the IAC during LS1edit programming.

It sounds like you have quality parts, I am concerned about your graph though - something looks wrong. I expected a smoother curve than that, whats your A/F ratio ?

 

ok here is the story i got. I was told that the timing was retarded inorder to make more street friendly, which is what i said i wanted. Now i kinda knew that retarding the timing will hurt my torque but i didnt think it would make it run this ruff. Again, i dont have any experiace with this cam so i dont know if it is loping harder than it is supposed to. I know the car is tuned cuz it start right up when it is cold and has only surged like twice in 300 miles, and let me tell it was a hard 300 miles and seem to be holding up. The reason for the jagged graph is that there is a problem with the dyno. I believe this cuz my car was delayed about a week (supposedly) but again, i have heard great things about the shop and im gonna bring the car in and some them what the deal is. Im gonna ask for the a/f, total timing and anything else i can think of. If i want them to advance the timing would they have to re-dyno it.

 

My didn't at first but I got my exhaust leak fixed and it started shaking the whole car. I was told the computer had to adjust to the change.
