Modular Powerhouse in Marietta, GA
They installed their "Mongoose" supercharger kit, and dyno tuned the combo. I called and made an appointment and, they installed the supercharger kit the first day and tuned it the second. It's been nearly a year now and the car is as strong as the day it was tuned.
I would not hesitate to bring my car back to them, and although its a 4 hour drive I wouldn't trust anyone else with tuning my car. Big thumbs up!
