Tune or stall problem? Im having a few issues with my car. Its a heads/cam/ 3600 stall car.
1.on the freeway at speed the car does not accelerate full out when i go wot, it kind of gradually and slowly accelerates. As if its not dropping to the lowest gear to go full out.
2. At times when i floor it from a dead stop, the car takes off hard but then the rpms drop extremely low and then climb back up rapidly.
3. When i tried to do a burnout once in drive, i floored the car and almost no power went to the rear wheels.. I held the pedal to the floor and it was almost like the car was in 4th gear not 1st (even though it was in drive at a dead stop). I had to get off the gas then start again before it acted correctly.
4. When both in drive and when manually shifting at times when the car is at wot and going from 1st to 2nd and 2nd to 3rd the rpms drop about 1k too low on each shift instead of staying at the higher rpm to have a consistent and steady pull. It kind of dies out just a bit on each shift..
Is this a stall problem or possibly a tune issue?

Cms tuned it so i highly doubt the tune is wrong, however during the tune the trans was acting up in the regard that it wouldnt easily shift into 3rd gear (it would redline)as i found out the drum was cracked but that has since been fixed.. Maybe he couldnt tune the entire trans due to the cracked drum?

Hmm yeah my first one from then went due to bad converter but I got an SES light and I got a lockup code. The next was the drum exploded but mine was the bullet proof drum. The last one lasted me a long time.
Hmm I would ask Ryne if he has any time to quickly take a look, he is usually very helpful.

so, i changed my rear springs and the problem seemed to go away completely. the story on the springs is this... the ra-tard i bought the car from took out the rear spring bushing, and then cut the rear springs almost in half. the car was always bottoming out, swaying ridiculously and all other types or rear suspension problems.... i went and put a set of 95 v6 camaro springs with the rubber bushings and it has been night and day... im thinking maybe with the previous cut spring the car was putting too much load on the rear end causing issues in acceleration and performance? any thoughts guys?

w the v6 spring/bushing it feels great... like i said im thinking maybe with the old *** 98 spring being cut and having no strength to it, possibly too much weight was being put on the rear end causing these problems of acceleration.... its quite possible a tire was getting hung up which may explain the one time not being able to do a burnout in drive.....
