1. I figure buying enough credits for unlimited model/year (for Gen3 99-07 Vortec motors) makes sense. THat's VCM suite with it's built in 8 credits, plus an additional 12 credits, for a total of 20 credits yes? This will let me tune unlimited Gen3 Vortec ECM's right?
2. I also often need to modify the AC control pin to instead control a second fan trigger. My regular tuning guy does this, but I dont' know what he uses. I assume this is something HPtuners can do yes?
3. VCM can be used to tune on the fly while driving? IE: Just plug into my laptop and mash the keyboard until I upgrade the HP?
Total cost for this would be just north of $1000USD ?
