hi, i have a 98' cobra with vortech 10 psi , 42 pounders (no FMU is unplugued sinse i put 42 pounds) and when the engine is arround 5K and up (WOT) the car starts poping by the exhaust looks like misfire, the spark plugs looks ok im using Motorcraft 22C Cooper no platinum, calibrated at 0.35 i whant to try autolite 103, the other thing i think it could be are the spark plugs wires and the coil packs they are the stock ones...
Any sugestions with spark plugs, wires, coils what to buy or what to do?

P.S. i have 75 HP shot but when i push it it pops even more and i dont have any fuel press problems in iddle 38 pounds and full 50 pounds so the problem is not there...

realy need help with this i have a war with some chevys...

I think you're experiencing spark blow out. Close the gap to .032 and see if that helps. If that doesn't help you may have to get a Boost-A-Spark to take care of it. Yeah, replace the OE spark plugs and coil too. Hopefully this will take care of your problem. If you go to a 12+ psi pulley you'll definitely have to get the BAS though.

what do you mean with the BAS?

BAS = Boost-A-Spark
