Studdering at 3500-ish rpm

[Wicked96GS-T]

Hey guys, I just got my 95 gsx back together(mods in profile) and I have some big issue that is not allowing my car to accelerate past abour 3500 to 4000 rpm. It will make maybe 7psi as boost starts to come on, and then it will studder violently and will not accelerate any more. I tested for boost leaks and found a small leak near my turbo compressor housing, but in the back somewhere I cannot see. Do you have any ideas what is causing the problem??

I had the same problem with my 97 Gs-t. I found that mine was caused by a bad coil.

Hmm, thanks for the tip, I will swap out the coils for another set I have and see if that works. Any other things i should try?

Fix the boost leak.

Fix the boost leak.

I plan on that, it's just in a spot I cannot see right now.

Def fix the boost leaks, and check all points on the ignition, coils, plugs gapped properly, wires. Simple things can drive me crazy, like forgeting to plug in the mas, durrr. Let us know how that 6076bb spools!

I have the same proublem at 2500 rpm . I have been pounding my head on the concrete for a week on this one . I think i have found the proublem. It seems that the oem fpr was stuck closed "I stuck it in a vice with a screw in the fuel rail side and tryed to get it to move open wouldnt move at all" I also noticed the smell of fuel in the oil that was just changed. So what i think was happening to me was that i had 55psi of fuel pressure in the rail when I should have had 27.. so the injectors were dumping twice the fuel they should have been ..hence a mega rich condition.. I am waiting on my after market afpr now ill let ya know if this solves my proublem..
