07 NNBS RCSB with AEM intake and Flowmaster exhaust cut before rear axle. Im changing to Corsa soon, though.

The motor seems much more responsive and revs much quicker. I can smoke the tires around corners and power braking is now possible. Torque management was removed as well as the governor. Shift points were adjusted for max power in RPM's. Im very pleased with it. It's not an aggresive tune like a cammed/ported motor would have. I wanted a reliable tune that would run 87-91 octane. I have 33in BFG A/T's installed, so it wont smoke the tires from a red light, but I didnt want it to anyway.
