PWR button?

[HBDVX]

Probably a stupid question but i was just wondering what the power but will do after i get my vz auto tuned/re-mapped tomorrow

the exact same thing as befor, change between trans settings.
The pwr button changes the trans settings and if the tuner adjust both trans tables it will behave differently if he doesnt change the trans tuning than it will be basicly the exact same

When i turn mine on the shift are much harder and quicker, also holds gears for longer.
