Hartmann Motorsports in Cali. said it could handle it just fine. They are the ones that did the RS4 upgrades. It cost me over $13k so far and I still need to install the fmic, fuel rails & pump, boost guage, ect...

I have an issue where it hunts for the gear 4/5 at around 80-90 mph and WOT. But if I upgrade my turbos I will def do a level 10 rebuild. Otherwise your just an accident waiting to happen.
