That's correct, but the M&M system we use for those cars have a different composition than the Akrapovic, and the header design is also very different.

So it's really safe to say that the 4.0 would benefit even more from a less restrictive system.

Would you mind sharing the logs from your tuned ECU ?
Would be interesting to see intake temps, MAF (so I can tell air volume) ignition timing and also lambda.

tks.

Hum .... you have slightly lower intake temps coming in, so this COULD, and I only say could as I don't know how this dyno operates with correction factors, but anyway lower intake temps will result in more power. You can also see the values in your Mass Air Sensor are higher than in the previous run, so more air = more power. All good and correct, would be also interesting to have logs of ignition timing, but this will do for now.

Thank you M3EvoBR!
So do you think they have done a good job? Or could be possible doing something better?

Looks like the tune gains is very similar to I what I see and achieve myself, so answer is yes.
Can't comment any further without looking at engine logs.
On the exhaust side, guaranteed you can have more gains with a different design headers and less restrictive exhaust.
