Also, what turbo are you referring to that has a lower backpressure? As far as I know, the M2 N55 market only has hybrids, are you 100% sure that these actually lower backpressure, any testing/data ? Remember, manifold is still the same.
No one can provide measured data there is no probe there...

But it's the physics and turbo engineering. Turbine is a big source for back pressure. Imagine you're riding a bike, longer the pedal arm is, less resistance you feel. In the case of turbo, that's the turbine.

Remember the V9 you made me one year ago? Dinan turbo can't even handle it on cool days, timing pulled all over the place. Same map, G Power is running on it brilliantly under IAT of ~120F, like the best log N55 can ever see. It's all you man.
