7GT2s all come in at around 540PS from the factory, +62hp from ECU tune only is too aggressive and not real power, there will be too much heat (from back pressure/boost) and the high IAT will retard the timing and drop the power off - not a good way of tuning a 7GT2...... IMO
u forget the margin of safety porsche puts in from the factory, as well as emissions related detuning, weather/altitude variance detuning, and especially fuel variance detuning. When someone makes a good base map for these cars, they are simple and tested maps that just take a way a little bit of the safety porsche has alotted, usually 98/100 times, the "tune only" cars should go just as long if not longer as a completely stock one as sometimes the tuning makes the car even better than from the factory in driveability/gas mileage...etc.

Would you like to guess what the EGTs are on my GT2 after 3 laps around Road America with a flash and stock 600 cell cats?

i wrote them last month, they replied within 24-48 hrs. i wrote their German address. i thought they didn't reply, but their mail wound up in Gmail's spam folder...
they're generally quite good at answering, from the little experience i have (ordering wheels from them)
