does raising the punch% decrease mid and top end speed?

[blueb8llz]

that does sound like what the punch control is doing sammus. it doesnt really seem like i lose much or any power when i have my punch % higher, i just need to press further down on the trigger like sammus is saying.
but jhautz, you say i lose acceleration with higher punch, i actaully gain acceleration because even tho its sending less punch, i just pull the trigger more, but when i have the percentage at like 30%, yes it sends more power, but itll just wheelie causing truck to slow down or lose control, even when i do throttle control , yea i can have my truck take off without wheelieing, but its going real slow taking off any more push on the throttle, and itll just wheelie, nuthing else i can do right? so people keep telling me throttle control but i can do that..thats no problem but the car will just take off too slow. am i doing something wrong here. all help will be muuuch appreicated!
