Anyone having misfires In cylinders 2 and 4 whole your fuel trims are off? I also recently installed the prl cobra race intake with the race file supplied by two step performance, now my ltft is -16 and I’m misfiring in cylinders 2 and 4.

I have had some issues... limp thottle but my trims are in spec. When I get this limp thottle issue, when it comes back, I get a large amount of gargle then a jerk... thats about it. It only happens with MAP 3 on tsp stage 1. Its related to a crap ton of heat soak. Usually when core temp 2 is around 140+

DRob is the people’s champ!:bow:
How would you re scale maf on a locked tune.
I also got tsp-1 and have PRL FP/DP and PRL CAI.
On WOT, the AFR goes to 9.5,9.6 which is super rich. I can see black smoke through my rear view mirror and I can smell unburnt fuel too.

Same issue has been experienced by all my friends who bought TSP

Now I plan to put new spark plugs and get the throttle body cleaned and take datalogs after that.

If I still get the same AFRs, I will request @D-RobIMW and @Two Step Performance to adjust it for me.
As without adjustment, it's useless for me

At what fuel trim levels(+-) should you start to be concerned?
