I would check your timing as well as doing a boost pressure test to make sure there are no leaks

Ok I checked out my wiring. On the 4 pin bosch relay I've got pin 86 hooked up to my fuel pump wire out of the ECU, pin 85 is hooked up to my ign switch, pin 87 is fused through a 10 gauge wire straight to my battery, pin 30 is a 10 gauge wire straight to my fuel pump.

I'm getting 14.5 volts to the fuel pump this way, granted I'm idling at 1800-2000 rpm.. (yeah I need a tune Saturday ) But when e-fans are on it drops to 14.2-3 volts. Quest alternator FTW!

hope this helps.

Ran the codes on the ecu. Got a knock sensor code. Found an unplugged knock sensor. Solved the problem in first, but in second I have the same fuel (cut?) starvatian issue in second!

And if one was unplugged, did you check the other one as well?
