Ok - dug out the dyno runs. I did these just over a year apart, at the same shop on the same dyno.

On the chart, RunFile_003.drf is the baseline run from April, 2017, before I had any mods in.

RunFile_006.drf and RunFile_007.drf are both runs from July, 2018, where the only engine mod I had on was the Akra DP (w/300 CEL Sport Cat).

Peak power is similar, max torque actually higher by 20ft-lb at peak, but you can see that the power and torque throughout the range is higher.

Definitely the biggest gains were below 5200 rpm, however even up to redline, for the most part, there were some (minimal, but still noticeable on the chart) gains.

From the drivers seat, the difference is 100% noticeable in the lower part of the rev range, top end, not so much. But we know the top end on the OG M2 is lacking, anyway, so it's not a surprise.

As a bonus, the car sounds awesome with the Akra DP + stock exhaust!
