That seems a bit low. I have seen 430AWHP with your same mods.

Best to compare with a stock TT on the same dyno.

With TIPS TT as well...we dont know what is the ratio for Tiptronic car and how much power it loose to the wheels...

Also been told that Tubi is quite restrictive exhaust...and Giac ECU can cause this as well...Proto Tips 997 TT with ECU and Exhausts dynoed at 500 whp or so but I am not sure on which fuel...

I got 388 hp and 420 tq at the wheel with my bone stock 997TT on a Mustang Dyno.

I am VERY skeptical of anyone who claims an hp increase of over 100 hp from an exhaust and ECU upgrade alone. More like 30 - 60hp and 70-80 tq at best. But you will definitely feel that increase - especially in the way the engine spools and sustained power across the power band.

To me, it sounds like you are just about right where it ought to be. Can you post the Dyno sheet??

AWD cars lose about 20% to the wheels.

I agree...I will try to get the dyno sheet from my tuner...+ 20inch wheels can loose some WHP...on E55 they caused anywhere btw 12-18whp...depends on a tyre set up...

Are your numbers to the wheel or at the crank?? I have never seen a stock turbo dyno over 400 hp at the wheel. A dyno at 445 hp to the wheel would mean the car is nearly 530hp stock at the crank. That is 50hp more than Porsche rates the car (480hp). If so, that is amazing. Were you running on a AWD Dyno or did you disconnect the drivetrain and do it on a RWD Dyno?

Either way, congrats!

These numbers are at the wheel in overboost mode measured on an AWD dyno.
