I think they just plain suck! Overpriced and all hype. I will never order from them. There turbo kits are way to expensive. Using stock injectors with 6 lbs of boost? Are they nuts? True, the same injectors are used on the E36 M3 (240hp to start with), so they are probably good for 280hp. However, I would switch to high flow injectors anyway. Better safe then sorry.
There E30 turbo kit is a joke. 14.7 1/4 mile on a 2.7i? Terrible!
