tune it for good performance.

lock the slipper for wheelies.

dont confuse the 2. you could put a novarossi 8 port in it, and if the slipper isnt tight enough still not wheelie. or you could put a .15 whatever in it, and lock the slipper, probably manage to get the front up.

these trucks have oodles of traction. and PLENTY of power.

as was said, read the manual, and for your engines sake, dont keep leaning it out till you get wheelies.
