I assume only your tips are really detuned, and if so, I wouldn't do too much underfoot due to rails and other crap will do that for you.
Keep your HIPS over your BOOTS(meaning get forward), hands FORWARD, initiate the turn from the knees, and maybe widen out your stance a bit.
Don't swing with your arms when you carve a turn, keep your upper body still and facing downhill. Only gapers turn with their arms(I'm talking about on-ground stuff, park jumps are different).
Feel the edge and see how grabby it is. Compare it to a knife edge. If it is similar, then you are golden. This is a good way to test, and if you really want a good edge, ask the shop for a race edge, which is 2°. I use that on my race skis and it holds on ice like no other.
Good luck.
