yes heffner couldn't crack codes so after shipping computer back and forth 3 times he just sent them the car. it took them 1 month to complete.

Unless I'm mistaken, the all wheel drive R8 has about 20% drive train loss, so the roughly 665 the chart is showing at the wheels would translate to around 830hp at the crank. Is that consistent with other's understanding? I think when people are posting the big numbers for the TT conversion they are at the crank. I am curious though about experience on drive train loss, since I want to dyno my V10 which has the APR remap plus GMG exhaust. If both "claimed" gains are additive, that should put me close to 600hp at the crank and ?? at the wheels until dyno'd.

an APR tuned 5.2 R8 with exhaust might pick up 20-30 crank horsepower unless it's full decatted etc. Even then, I don't thin it'd be much different.

So more like R8 GT type peak hp (550-560) rather than 600.

Thanks g-force. Sakimano, I am curious how you arrive at the 20-30hp gains at the crank with the APR tune? Are you disputing the dyno chart they post on their site comparing with and w/o the tune. Without having dyno'd mine before and after, I have no data other than what APR and GMG post on their sites. However, I have found on a rolling launch, my wheels now break loose where they did not before the tune. That seems like a significant real world change.
