How much boost are you running, what turbo are you using, how built is your motor, are you using stock coilpacks, and are you sure its not fuel cut?

Re: blowing spark (sr kid 88)
Slightly off-topic, but I don't get why a lot of people are having problems with spark blow-out...I have a 10:1 SR20DE+T with a stocker T25 @ 10PSI and I run with a .040 gap (DE gap is 0.044), and I don't have any problems. That's even with a distributor! You guys with COP ignition systems shouldn't have any problems...
Of course my T25 @ 10PSI isn't anything compared to a GT30 @ 16PSI, but still... I have .040 gap!
