just installed a pacton novi 2000 on my 96 cobra. having problems with the plugs i think. i started with NGK TR6s(copper) gapped @ .032. the car pulled hard only too 6200rpm. a local mustang shop with a dynojet said the spark was being blown out. i set the gap too .025. it pulled hard too 7000+ but power down low suffered. i just put in NGK iridiums, set the gap too .035,(which the shop said to do). the car now only pulls to 5200rpm. what plugs should i run, what gap, and would an MSD ignition solve the problem when keeping a bigger gap? thanks for any help.
