Breaking up past 6000rpm pLz HeLp
Hello,
Car is a 97. Stock motor. Running a gt2554r at roughly 10psi. Mustang gt500 injectors. BKR7E plugs gapped to .025. Stock coil packs
The issue: Car runs great untill i reach roughly 6000RPM at which point it starts to break up. I swapped out coil packs with a known good one and same issue.
I'm trying to attach a log of this with my tune.
Any help is appreciated. Let me know if there is something else I should check

Very good find! But I'm confused about how you found it. When I look at his spark advance, there is no spark retard. I looked at every SPK graph and there are no modifiers.
I ask because I'm seeing a similar thing.
OP: Do you hear the a BBBBBRRRR sound out your exhaust (which I believe is indicative of spark blowout)?

I did not hear a "BBBBBRRRR" it sounded more like little misfires, exactly the same as when my wrx had a bad coil.
Thank you for spotting that I forgot I was playing around with the rev limiter -.-
I will change the limiter and see if it solves the issue. Will report back when it stops raining.
