So how are things going? Did you finish comparing them? Did you find the problem?

So I used this maf cal for my jbr powerpath stage 1 / corksport aluminum turbo inlet and my ltft and stft are within +- 2% which I'm thrilled about while driving but my problem is when I get off the gas pedal and coast / sitting idle my ltft goes up to 14% . My car idles at 1.13-1.16 maf volts. Should I do adjustments there?

Post a log and let's see. You may have a vacuum leak or it's simply how your car works.

Recommended parameters / what kind of driving style log would work best?

Most importantly log those situations that concern you... so an idle log (with the AC off) at least 30 seconds long, some normal driving, coasting, whatever those situations are.
