i do realise that there is a lot of work in proper set up tuning, and expected QT to be an adjunct only, but the Vipec literature is bold and unambiguous. maybe it needs to be changed slightly so expectations aren't raised. my question was just cost vs benefit ie if it's really such a great time-saving measure why Vipec does tuning still cost the same. i understand from what you guys are saying that QT is good, but probably doesn't save that much time, so it makes sense that it's not going to change the cost of tuning all that much.
thanks for clarifying
