toronto,
I installed my 190lph pump and 650cc injectors today, install went fine, everything is in there good.
Car cranks over and starts right away no hesitsation, rpms go up to about 1200, than drop to about 900, than drop to about 500, that the car just shuts off.
I have the base setting on the maf-t set correctly. I did a boost leak test, best i could with a bike pump :rolleyes:, anyways I was able to build about 11-12 psi in 25-30 pumps, and it took about 20-30 seconds before it dropped to 0.
Any ideas on wtf is going on?
 
Do you have any fuel control. AFC, AFPR? Your dumping so much fuel into your motor it not even funny. I bet your A/F ratio voltage is like 832432.12312 ROFL ROFL You need to control it. With more than your MAF-T
