Thanks for the help guys.. As far as the N/A being high imp.. I think they are low emp. they run my Z perfectly. if they were high imp they wouldnt work right at all right? so far the Z is running really well. 14psi and 12.0 air/fuel.. But down low and cruise she sits around 13.6-14.0 which is rather rich.. but being a afm car I will live with that till I go stand alone. She is faster then she ever has been thats for sure . with my old setup stock inj, 11psi and 2.5" exhaust I ran a 13.0.. I am hoping with the 3" exhaust walbro fuel pump upgraded injectors, 14-15psi of boost will put me mid high 12s..
