i am installing dual cp-3s on my 03 2500 4x4 6 speed there are a few things i dont like, the throttle position sensor relocation bracket is cheesy and the holes dont line up, i had to redrill, also the bolts that came with it should have been at least a 3/8 and about 1/4 inch longer so washers can be installed on both sides and by the way you dont need lock washers with locknuts, looks like i will have to fabricate my own bracket this one looks like it wont be long untill vibration destroys it, next is the electronics, they look like they cost about seven bucks to build the ones i got, i was told they were very expensive ??? i will be using someone elses electronics... .
