Go with the company you can read about, everyone knows about and knows how the engine and ECU works.
For me it would be R-tech, they are leagues and leagues above any other tuner who tries and maps cars. Each map is unique to the car and they know the cars inside out.
Badger 5 are up in your area too? Bill knows what hes doing aswell....those are the only 2 I would get to map a car.
The 25+ pages of great feedback of R-tech and their customer service - free map updates speaks no ends.
