RE: Wheelies??
I have a stock Savage 25 LE and mine will wheelie on grass all the time. On pavement, it will pull both front wheels off the pavement, but does not really wheelie. I just recently got mine broken in and finished tuning and it has a lot of power. I am now about 18 tanks into it. You should be able to tune your HSN until it is running really good WOT (shifting and everything) then adjust your LSN for takeoff. When you start tweaking the LSN is when you will start being able to wheelie.
