hypertech tuning

I finally got the hypertech tuner for an 03 chevy. Well i have put it in but i dont think that i set it up right becuz i cant really feel any difference. I was hoping that someone could help me set it up for shift points and gear ratio to manipulate the system since it only goes to 33" tires. I am running a 5.3 with stock gears, 36" tires and no shift kit, if you want to help and need any more info just let me know thanks :shake:
