bucks @ 4000 rpm under wot
 

Hello all! My car bucks @ 4000 rpm during WOT (feels like I hit a brick wall) then continues to accelerating. If I throttle below 70 percent it'll make it to redline no problem. I hope its not my coil pack. Attached is my log and msq.

1999 Miata sr20 turbo
NGK4644 gaped ~.032

if you're on stock ignition and more than 10-12psi, you probably need to gap lower.

or just tune, i didnt look at your msq/log.

Thanks for the quick reply. Yes I'm on stock ignition. I'm running waste gate pressure which is about ~7 psi I'll adjust my gap later.

Maybe ~.023 sounds good?

Overboost protection
