hey guys i recently put in a manual boost controller in my rb20 32, and looking at my boost tacho boosting to 12psi is good, happy with response etc, but as i turn up the boost to say 14-16psi the car feels like it doesnt move and has trouble boosting, no G force whatso eva.....
btw. its got turbo back 3" exhaust, FMIC, pod filter, using motul 4100 oil and standard ngk plugs
any ideas?
