I just put a procharger blower w/intercooler on my 94 z28.. The car runs great, but it don't want to start.. I have to crank the hell out of it to get it to fire.. I'm pretty sure its gettin too much fuel, but I'm not positive. The car started perfect before supercharger install.. any suggestions on what it could be??? I thought about buying bigger injectors 30 or 36lbs. and tuning out my fmu.. will this help?

Also what size injectors would you recommend? Basically stock w/ exhaust and 8lbs. blower kit...

My fuel pressure gauge shows about 37 psi at idle and jumps to about 60psi at wot... if it helps..

 

I would recommend strongly that you get dyno tuned ASAP. If you don't you will thrash your motor with improper tuning and a S/C.
Been there done that.
