Well i have been trying to get rid of my spark problems at WOT. I replaced the plugs with the 4644 NGK's and gapped them down to .022 and still have problems. It has gotten a lot better with the new plugs and gap. I'm running a 92 miata with a mspnp, 460's,190lph pump, lc-1, 9psi. should i gap the plugs down anymore?

 

If you are having problems at that gap, you should start looking elsewhere. What do your AFRs look like?

 

they jump up a bit from low 13's to high 15's when it cuts, should i post a log?

 

Always

 

Well thur's your problem.

 

+ 1. Get your afr's to the low 12's - mid 11's....I'd say your running pretty lean.
