I have an h22. I am running about 6 pounds on a t3/t4 turbo. Its breaking up a little around 4500-5500rpms when I turn the boost to 8psi, Its really bad I'm pretty sure its ignition related, anyone know what a good plug gap setting would be?

arf is 12:1 all the way across the board.

Just keep dropping the gap until it goes away... try .025"

 

Yeah, anything around .030 is good. What is it gapped at right now?

 

.035, it was ok untill I got it tuned, My first run I made 257hp 216.6 torque the arf went off the board a couple of times, It was way off. when I got it set to normal the hp was 281 and torque 245.7 and it started too run like **** then,I figured the more hp i ran the smaller i had too make the gap am I right?

That's correct. It may be that your stock ignition system needs some help. But I'd start with the cheaper things first and try closing the gap a little.

 

h22 ignition kinda sucks so you usually have to gap them pretty tight...

 

ok thanks for all your help.
