Has any one put one in the 7th gen SS. I'm thinking about getting one has anyone put one in they car and is it worth the money. I was looking at the cortex and tuner.
Don't do a chip. The tuners are better. My Dad has a Diablo Sport tuner for a Mustang GT, and it DID make a noticable difference when tuning for premium fuel.
Quick question here, whats the level of difficulty of useing a tuner like the "HP".
Most of you know a good idea of how experienced i am with my car, do you think id be able to use one??
