maybe it is..............mafless vr ftw. lolrtc.
If not tuned it is because MAF is reading X amount of air but more is actually going through the TB now, so the auto shifts earlier as it judges shifting by throttle position idk I am on my phone annoying to type out. Basically auto shifts earlier than it normally would at the same throttle position as more air than what it is tuned for is going in I believe?
Meh Steve can explain lol but tuned was much better and dat throttle response mmmm
