I realize, but that doesn't change that you really can't make more than 540-550HP on the stock turbos... The intercoolers don't allow the truck to make another 40-50HP...

I was suspicious of this as well since another 20hp was too small to consider until I spoke with the EVO guys. They told me that I should see more power with the CTTS ecu program than the regular CTT based program due to intercooler and ecu programming differences. Evo recommended I call GIAC to confirm and will do so. Where did you get the information that the existing turbo's could not make more than 540-550hp?

I could be wrong, my questions in this thread really are questions.

I suspect what you are saying is correct Evan, it makes sense. However, I was hoping to be surprised based on what I was told. I have not heard back from GIAC yet, but will post the results.

CTTS-GIAC ecu upgrade
It appears that the EVO guys were under the wrong impression. GIAC says Porsche already optimized the Cayenne Turbo S programming to achieve the existing gains over the regular Turbo. Thier program would only add approx. 20HP on the Turbo S. I stand corrected.
The search goes on.
