ok i just hooked up a 100 shot today (NX) and put in some ngk tr6's. i gapped them at .045 cause thats what i was told with the msd. the car seemed to lose power without the nitrous and wasnt really what i was expecting with it. also the third time i hit it , it backfired threw the intake and blew the boot off????? please any opinion would be helpfull. thanks

ok i just seen the thread below mine and i guess most of yall run about .040 with the msd. would me gapping mine at 45 make that big of a difference or do i need to take them out and regap to .040? thanks

 

Personally I run with a .032 gap but it all depends on your compression ratio there.
