ok guys i have a 2000 camaro and it was stock with 273's.... i changed to 410's with lt headers,slp maf,lid. now my car wont shift 2-3 wether its from a dead or from a roll or evan if i try to manually shift the gear and i dont know whats wrong. i did change a few things but i dont know what is causing it. and from a 60 roll it feels like it down shifts then shifts back then down shifts again. i have tried to put my mph shift points real low and real high and it still wont shift. here is a tune file.
