Efi logics in bethel ct! Chris is a world class tuner and efi has some sick race cars. I don't think you can go wrong. I like the fact their dyno is low reading aswell. I would do some research on the tuners themselves from the following shops and decide for yourself. Efi logics. Area 1320- road and dyno tunes. Psi proformance. Autoperformance solutions. Mspt. Rt tuning. Most of these shops should give you a safe tune but the question is who will give you the smoothest most functional and powerful while still being safe? It all comes down to which tuner has the most knowledge and experience to get the best tune.
