its great the thing flies there, is less turbo lag thanks to the diverter valves the car is like a rocket. You get the same kick as at 30 mph at a 100 mph. The exhaust is great the sound is unbelievable, you will want to stat the car just to here the rumble.
i dont know about other chip manufactures but oct isnt a lie it is true performance. The thing feels like you are in a fighter jet.
