ure car will need pro version, if the shop is tuning it they should have the software needed. Also only real reason to go with trifecta is if you have a turbo cobalt or if you dont havea tuner near you, only reasons.

paying the extra for the vcm suit is a waste then you are saying?

when you purchase the pro series the vcm suite is part of it. The standard is also the suite but you cant read alot of things with it. U mainly need a wideband. U can accomplish this with standard as well by using the ac signal wire for a wideband by splicing the wideband feed to the signal so that the standard can see the 5 volt signal wire feed. I hoe you understand. Id just get the pro.. Worth it, if you are doing the tuning but i dont recommend it unless you know how to, dont do anything even if you know the basics.
