I just got my first 2G GSX with minor mods. FMIC, recirculated bov and cat back exhaust. I’m having an issue that affects just driving the car. Basically even just a tiny bit of boost between 3K-4K rpm the car loses all power. I can be building 10psi and just goes nowhere like I’m dragging the brakes. But I can drive through it no problem with no boost. I just put spark plugs in it and gapped to .28. After 4K rpm all boost hits and pulls good throughout the rev range no problem. The car has no boost leaks, good compression and turbo is fine.
