well install was quick and easy, took me like 20 mins to take everything off and back on. started the car sounds differnt. even the intake sound is different has this new whistle to it. idles a lot better. like it was said before its like driving a new car and u have to re-learn to drive it. im very happy with with. its very touchy which i like. i want gas and pow its there. no delay at all. deffinetly more noticeable out of the ox out of many of my mods. even friends said the could see a major differnece in feel. now they all want one.ill give it a 4 out of 5 just because the screws that came off the stock TB for the side connector go in a little tight and i dont like that it felt like they were being threaded wrong.
