PRL with Race MAF Getting High STFTB Value and Low Turbo

[smokeelaa]

Just installed PRL Cobra with the Race MAF and used Ktuner Race MAF setting.

When testing the car I am getting STFTB values in the 40s and the turbo is only going about 2/3 to 1/2 as high as before the CAI was installed.

Anybody have any ideas on what I should be looking at for this issue?

Forgot, also getting higher rev at idle (between 1000 and 1500 rpms).

Sounds like you don't have a RACE MAF or have another issue to look for, like a vacuum leak if it's pulling fuel.

Definitely have the Race MAF. I ended up re-checking all of the clamps on the intake and they seemed OK. After doing so, I still got the high STFTB numbers.

I decided to try to re-apply the tune since the first attempt ended up triggering a ECU recovery before it succeeded. After re-applying the tune, the numbers normalized and the car ran as expected.

Thanks for your help with this.
