Peak wheel-hp: 180 @ 5450-6175 rpm
Peak wheel-torque: 202 lb-ft @ 4300 rpm
Maximum wheel-hp gain: 14 @ 4300 rpm
Maximum wheel torque gain: 16 lb-ft @ 4250 rpm
*Install process: Software flash through the OBD-II port.
*Pros
Huge power and torque; the car will now spin its tires in second gear even with the limited-slip diff Factory smoothness and no dead spots or hesitation
*Cons
GIAC tells us the turbo can't be used to its full extent because of high intake temperatures
Price: $550
Notes: In the upper rev range, the car is restricted to just over 16 psi because of intake temps. With a larger intercooler, GIAC is convinced more boost is possible, meaning more power.
*Conclusion
As with most turbo cars, the software is the first big step. While we saw gains from the intake and exhaust, our testing made us think a front-mount intercooler might be an even better first step. We'd also recommend Alta's full turbo-back exhaust (instead of just the cat-back) to maximize power. All components are nicely engineered and well built. None require a sacrifice in comfort or driveability for the sake of performance.
