Hey Big Large, If you have not bought cai/predator yet I have one for sale. I just put on a Saleen supercharger. So I have a C & L 10699-05P with Predator 7140.
It has about 4,000 miles on it and in great shape. It was a great upgrade for my 05 gt. It has the C & L tune tune on it for 91 or 93 octane. Big change in throttle response. I raised the rev limiter, recalibrated speedometer for 4.10 gears and bigger tire size. New they are about $700. Let me know if your interested.
