the price i got was $6800. they said with the dinan stage 3(software@cai) i already have, it should pump out about 50hp. its about 3,000 cheaper than the dinan, you get the high flow cats and pipes all the way back to your own mufflers. the dinan only give 26hp without the throttle bodies.(so they say). im wondering if anyone has some solid proof. sounds pretty good.
