What I'm saying is that a stock 2015 pump will support 1550 pw. If the II pump actually is 55% over you should be able to get a lot more out of it.... But I assume their claims aren't as good as they speak. And I would say your in the 600hp area.
Our 2 Turbo's are pretty close. Gear ratios are the same and not sure about tires. 1649 was just under 600 and 1710 was 603 Running the Elite Tune FYI. 2600pw well the other 2 people are dead. LOL
