Bone has been running his VECII and the flash for quite some time now without incident. When I was kicking around the choice, I boiled it down to...
First would I need the VEC? I wanted the SC, so I wanted to be able to make adjustment's here at the house if necessary with the VEC and laptop... it hs paid off already to have the ability to do so.. The flash would have to be sent out. Not to confuse you a PCM can be re-flashed for SC applications.
Cost vs hp gains associated with either taking the overall goal of the truck in mind. (I was not going nutso with a piggyback system, tuning ability, ect. if all I was going to do is a nice exhaust, CAI, and headers.:dontknow: A flash would have been fine, that's $400 - $500 that can be used elsewhere..
The VEC allows you to make adjustments, the flash does not allow you to tune (to my knowledge) without sending it out for adjustments. :dontknow:
The QC's seem to get more benefit from the flash, for the aforementioned tranny, torque mgmt, adjustments that the VEC can not change. I do know Bone is tuning his truck via the VEC, over the top of the flash.
Hope it help's:dontknow:
