Spark Plug Gap

[Hahny]

I'm running NGK UR5's gapped at .030 @ 20lbs of boost on 98 octane. Does this sound about right or should I close them up a little? Let me know what you guys think. Thanks

Try 28. Get alky and go for 27psi (small increments). You won't be able to wipe the smile off your face.

Will do Pronto! Yeah, alky is on my to do list, but just like anything else it takes time and $. Thanks

If you're not blowing out the spark there's no need to close the gap.
