FRPP does not currently offer calibration for automatic-equipped '11 GTs when installing its supercharger kit. To finish our installation, Chris Johnson of SCT Performance made the changes to the Copperhead ECU using our in-house Dynojet. After about a day in the shop, Johnson conservatively tuned the GT, which laid down 492 rwhp and 417 lb-ft of torque using the SAE correction (93 octane was used). Once the car returns from the SEMA and PRI shows, look for us to extract every last horsepower we can from our current combination, as well as all the track-testing it can handle. Johnson estimates there is another 20-40 hp hiding in the cam timing alone!
