For the money, you cannot even come close to the TFS kit. It allows you to bolt it all on and go. Then you can easily upgrade your injectors/maf later. It will net you around 290 rwhp, and have potential to go MUCH higher with some boost. Look around on Stangnet and Corral, LOTS of people have bought this kit and Ive never heard of anybody not liking it. One of my buds on Stangnet did it to his car and he swears is pulls harder than the 125 shot he had on hsi stock motor.
