I've been looking around FOREVER for a chip or for the Shark Injector. I wanted some opinions on each. I heard with the injector, the car feels sharper! I just dont like the fact that with the injector you can't update it and you cant resell it cuz he only sticks with the first VIN # it recieves. So I wouldnt be able to undate it if I got euro heads etc. I have my own CUSTOM BUILT EXHAUST thats going on sometime this week! Thanks to Da Vinci Motorworks. If someone posts on how to put a sound/video clip up here Ill do it and you guys can hear it!
