Just bought a 2020 supra 2 weeks ago with 20k miles.. installed catless dp and flex fuel kit.

Took it to get Dyno tuned. They said the car wouldn't make power since it kept trying to pull timing.. made about 320whp baseline.. no boost leak as per tuner and compression test checked out around 179-180 for all cylinders

Don't know where to go from here.. car drives fine , no loss of power and no cels really besides for the cats.

Was told it could be a bad engine- pitting on pistons.

From tuner that tried to tune car - Attached is the dyno graph and a log with the car tuned on our conservative basemap. On the graph, the first 2 runs are on the stock tune (red & blue), and the third run (green) is tuned, before we stopped the dyno session. Unfortunately I did not log the stock runs.

Log and graph below

Not a Corvette.
There is not timing in that log, just timing retard so it's hard to see if the issue is them just trying to cram too much timing in the car or something else.

I found a lot of "BMW" tuners don't realize the 2020's are higher CR and try to run 21+ amount of timing into them.

EDIT: nevermind, there is cylinder 1 timing, and it's wayyy low.
