I just wanted to let everyone know of the exceptional service I received from Jim at Turbo Horsepower. I ordered his twin 57MM kit for my cobra and his service was far above and beyond what I ever expected. He was always availible by phone and answered e-mails very quickly. It is hard to find a business man these days this honest and he gives his service after the sale also. If anyone is considereing a turbo kit, be sure to give him a call and talk your plans over with him, he is very knowlegable and will sell you on his knowledge, not on his sales pitches.
