15psi is fine.

Well, just finished the rewire and upped the boost to 15psi. Made quite a difference.

Heres the problem: I shifted into 2nd at about 10mph and nailed it to 50mph, it cut out like 3-4 times (very brief) like the engine is missing. Is that detonation or fuel cut?

I am still running the stock plugs and wires. I just ordered accel 8mm blue wires and intent to pick up some ngk's when they get here. Could the plugs wires be the problem cuz they cant handle the extra air and fuel?

Im really worried about detonation.
