The car ran like crap - coils arching. So I did the LS2 coil conversion. The car still bogged at "FOOL" boost, so i figured out it was a bad TPS. Changed the TPS and now i'm getting a boost spike to 10-11psi and then the boost drops back down to 8psi and stays there. If i turn the Blitz controller off it stays at 5psi without any spikes. Does anyone have any pointers for me?

S14 - RB25DET S2, freddy mani, fmic, LS2 coils and exhaust, otherwise it's all stock.

Any help will be appreciated, but i'm suspecting the TPS needs to be adjusted which I haven't figured out how to do yet even after reading some how to's
