Have a wierd problem and nobody knows the solution...Need Help!! Ok I put Hooker Longtubes on my car and a Cam (222/226 566/569 114) and 2 months later after running the headers open I go to have the True Dual setup with X-pipe put on and to have LS1 Edit done. I get the car back from having both things done and as soon as I take it out and get on it the car starts studdering almost feels like it wont shift and tacking out but it is in the middle of the rpm's right after I get on it and won't quit doing the studdering until I get off of it. Right now I have asked a couple of shops around me and one of the owners has no idea (shop I got LS1 Edit done at) and another very respectable shop owner said I need to get a Torque Converter because of the cam.
What is the problem with my car what would make it do this?

Re: Have a wierd problem and nobody knows the solution...Need Help!! Have them put your stock program back in and see if it still does it. If it doesnt its your program, if it does they messed something up putting the exhaust on.
Re: Have a wierd problem and nobody knows the solution...Need Help!! Maybe the open headers made it learn a weird
air/fuel map (air reversion can really mess
with the O2 sensor fidelity). Maybe you got
tuned this way? Wasn't clear. The extended
exhaust eliminates this and the mixture needs
to be remapped. You might try to force a
relearn, or you might try driving around,
teasing the trouble point and see if it learns
its way out of it.
Sure sounds like it's not delivering fuel at
low vacuum / high load.
