Hello guys,

Need some help on this issue:
I have a Vortech V2 superchared AP1, tune is great, AFR is steady along the whole RPM range around 12.0
the only problem i'm facing is a fuel cut at around 7500 RPM then continues perfect till 9000
and it only happens once every like 3-4 full throttle runs. i can't seem like diagnosing the problem
i moved to one step colder spark plugs, then i changed my coils thinking it could be the problem, but no, the problem persists

any suggestions, which spark plug should i use for this setup
I'm using haltech PPP by the way

thank you

Did you get the software update for the haltech? There was a huge thread about guys having a similar issue in the forced induction section. I believe it was fixed with a software update.

I'll try and get back to you. Appreciate it.

Ya there was a software update. I am not sure it actually went public yet. Matt Wright said that he would get follow up with the updated version whether or not it fixed the problem. I believe the new version is 1.12.14 experimental. I may have it in my email if you want to give it a shot. Send a pm if you would like the forwarded email.
