The Dinan Sport Tuner? How do you like that on 91 gas?

I couldn't get intercooler above 26 or boost avouve 13.3psi
I’d be worried seeing n55 AFR @16+. Probably explains why boost is lower.

That screenshot looks like he was off throttle at the time.

~ 22psi peak is more likely to be a spike due to overboost on upshifting - more prevalent on MT than DCT cars AFAIK.

Does the AWRON gauge give you boost curve through a pull, which might show the above spike, followed by boost re-adjustment once higher gear is selected and pedal / load is @ ~100% ?

Mine peaks around 19-21psi on hot florida weather but its just a peak and then it stabilizes itself at around 17psi. I do have a catless downpipe on a stock tune.
