That are Corrected Engine HP numbers, not WHP. And they are very low then.

You should be able to reach about 370 Wheel HP on Mustang dyno or 426 Wheel HP on DynoJet with that turbo. That will be about ~470 Corrected Engine HP. So you are missing about ~60hp...

Also your torque numbers are very low too, and turbo is spooling really late... You can get more power and torque even on stock evo9 turbo. That makes me ask you a question - what boost are you running? That turbo show nice numbers at 1.8bar peak, tapering to 1.5 at redline on 2L engine.

Here is an example what power and torque you can achieve with that turbo, and how fast does it spools. That is Mustang dyno graph, which reads lower whp than any other dynos. Let me know if you need any help with your tune.

I had some experience with comparing US to EU dynos and it seems that ie 400 BHP on MAHA dyno (MAHA numbers are respected by most car manufacturers) is similar to US 400 WHP. My friend from Poland tuned a lot of cars in US.

WHP is never similar to calculated engine HP.

EU & US dynos are using different SAE/DIN corrections and maybe thats the reason.

The reason is that calculated Engine Crank HP is always a 10-25% bigger number than a real Wheel HP because of dyno+car transmission losses etc. However Wheel HP may differ from dyno to dyno, like Mustang whp and Dynojet whp for example.

His WHP is in between Mustang and Dynojet, closer to Dynojet numbers. 340whp. His engine hp is a calculated number based on specific corrections you were talking about. You can have that calculated engine hp number for Mustang and DynoJet whp by dividing measured whp by .78 and .9 accordingly, for awd evo.

To make it closer to the real world, skipping all the calculations - that car will show ~320whp on Mustang and ~370whp on DynoJet.

Boost leak that car and check the AVCR settings, your ARMS 7960 hits max boost over 5k RPM. It's like 1500RPM too late.
