Misfire
 

I’m having a misfire around 5000 rpm at WOT and for like a fraction of a second and after the misfire the car goes up to 7 grand with no problem, and when I turn on the meth you can feel it harder at the same rpm. The car made 662 rwhp and 550 rwtq on 93 octane with the misfire so is pulling very strong.
What I done so far change spark plugs and coils put the car on the dyno check tune and wires from the MAF oh and no codes.
The car has, sct 3000 maf, vortech TI-trim, granatelli connectors, and stock COP.
Can someone help thank you.

What did your tuner say about it?

I second that question.
It's possible it's pulling timing at that rpm and that's what you're feeling.

The tuner still working on a fix, and the car is not pulling timing

What plugs do you have? And what's the gap set at? Possible the spark may be blowing out

NGK TR6 at .25

Misfire
 

Fuel? E85?

Edit: nvm I see you're on 93 oct. I would talk to the tuner and see what he recommends. I know someone running some tr7's at an 18 gap but he's on e85 and making more power than you. I would talk to the tuner. Maybe a different plug will resolve your issue

The tuner talk about going with a TR7 will see if this work.

You sure the gap on it isn't too small? I accidently gapped my plugs on the eatonswap @ .022 one day and it misfired like crazy. That's with the TR6's

Find out what the problem was the alternator is only putting out 80 amps

Re: Misfire
 

every car is different. Had one cobra that demanded .25 gap and another that wanted .28 Gap

If it is spark blowout. Go BRISK plugs,:thumbsup:
