I'm just wondering, we plan to tow with the QC and do mild mods, delete cats, headers , cat back, and filter. But will the Vec 2 work with the QC and automatic, or are there going to be another different programer for the QC? I have allready noticed the QC seems to be much richer than the RC it seems, so I was thinking that MPG would increase as well as towing at cruising RPMs. Your input would be appreciated, thanks
