Classic 3800 rpm hesitation problem
Ok so ive done lots of research on this subject and i have now found out my car has this problem.
Basically whats happening is that my car hesitates right at 3800rpm but then continues fine after.
What i want to know is through you guys's experience with this problem whats the best way to fix it? Ive read running new grounds helps. Also what about if i replace my secondaries? Isint this where the hesitation is coming from? possible bad sec. injectors?? I was planning on replacing my sec. with some nice 720cc injectors from RP
Let me know what you guys think
Thanks

I had that problem and got rid of most of it with running a few ground wires, cleaning the battery terminals, and running some Gunk fuel injector cleaner in the tank while driving it harder than normal (above 3800 RPM).
Do you have a way to tune those 720cc injectors? I think it will run really rich with the stock computer. I didn't read your mod list because I was too lazy.

This problem seems to have various causes with various solutions (although porting the wastegate isn't one of them). First try adding extra grounds to the ECU and boost sensor (read this page), as well as additional grounds for the block and battery made from 8GA cable. While this works for some people, it didn't help me at all. However removing the injectors and having them professionally cleaned completely cured the problem. Don't waste your time with in-tank cleaners for this.
