I also have a 2007 GT convertible. I found that the combination of flow master, K&N style air filter, E3 split fires and Royal Purple synthetic oil gave me about .6 fast 0 to 60 times. The biggest felt gain was the addition of Royal Purple!
Hey there, I have the 2007 version of your car, I am interested in modding my car any suggestions? I see you have the crab intake and an STB, which I am not entirely sure of what that is. My question is, if you don't me asking the approx price for the intake and what positives have appeared from the changes you have made.
