In usual Heffner fashion we wanted to make a bolt on kit that looked like it could have come on the car from the factory and can be installed quickly and efficiently. Our first R8 twin turbo gave us 536 whp.

 

This is a 183 rwhp gain (more than a 50% increase!) over what the car had when it came in with a Stasis exhaust and Revotech ecu tune. 

A 100 octane program yields nearly 600 rwhp which translates to a high 10 second quarter mile.
