M370 with High flow mods.

I've still got mine on, it's been on for many months, and I'm happy with it overall.

I think all of the results you have to take with a little grain of salt. I don't know that anyone's every done a *perfect* comparison (same day/dyno/conditions, both manifolds, and each optimally tuned with different ECU settings), and even then we'd need such a perfect comparison for every set of supporting mods to boot

The general trend of the evidence we have, though, is it helps increase torque area under the curve all through the middle. That counts for a lot more than some tiny fraction of power at the very peak of the RPM range (where you're unlikely to usefully be for more than a split second in real conditions).

Actually, the two runs I posted are about as close as you can get in ambient conditions. Only oil temp and IAT's are unknown. Both runs are in same gear too.

Oil temps were between 180 and 185 during both runs. IAT's should be identical. Industrial fan was blowing through the front bumper and two shop fans blowing exhaust out the door.

Oh I missed that, good job

You did run a separate optimized tune for each right?

Yes. And this is on a full bolt on vehicle. The gains are consistent no matter the extent of mods. At least when comparing NA.
