tuning is not easy at first at all. i lost hair and sleep over learning, read, read, read some damn more, then your scared to death to make a change lol that all wears off pretty fast.
being im not a youngster myself, might have added my learning curve.
the t app, my phone goes on a windshield mount, easy fix right there.
when tuning the laptop sits on the pass seat, its only there to scan your parameters. your not tuning on the fly, you need to pull over park and look like big chief with a lap top editing the file. lol
in my regal i got a handful of live gauges on view with my DHP tuner. the KR gauge flashes red if i make or pass 2º of KR. and i can see that out the corner my eye. my other cars got a supercharger, (KR is death for it, knock retard that is.) my avatar pic is its engine.
now next week im getting a HP tuner, so all new learning curve going on.
