Jeff came to us with a factory Ecu and had been through multiple tunes with online tuners and just could not get it running well. After a Haltech R3 and a few upgrades this car is running great.

S650 on the dyno. We installed a pair of Stainless works long tune headers. And the car had a JLT intake system. We did our 93 octane tune with the roll race auto up shift feature when using the paddles. 462whp at 7300rpm is better then we normally get with the S550.
