Bet its your plug gap.

I was experiencing sparatic misfiring, I cleaned the grounds, and the dizzy cap, and I think its cured. ???

Re: d16y8, 14b @ 9psi, breaking up at high rpms
 

I put a smaller spring in the waste gate and at 6psi it doesn't break up and pulls fine to redline.

So at 9 pounds it was detonating( i assume, and was not ignition related but just detonating) but I don't know if its from too much timing( very possible due to afc) or not enough fuel.

At 9 lbs. I was running -35 or -30 on dsm 450's from 5k-redline, either setting it would break up, so it seems like too much timing. Thoughts?

I'll look into the ecu stuff, the prices were from xenocron and included new injectors. Thanks for the help guys.

its your timing and your plug gap listen to people like me that have been down this road to many times to list

The gap is tight (.028, .030), I'll try pulling some more timing. Thanks.
