big,big problems. well uninstalled the 3815 no problem,back to stock. loaded the sct tune, didnt have any guages and all my lights on the dash were on(check engine,fuel,and such). took truck for a little ride anyway. truck ran great. better than with the 3815. so i come back home and uninstall the sct.(back to stock) all guages are working again at this point. still have the check engine light on, clear the code. so i thought gonna try it again, maybe i did something wrong. with the tune installed it did the same thing, no guages and such. tuned it back to stock. thought well i will try it again. loaded new sct tune again. no guages and such. truck has great throttle response. so went to take it back to the stock tune and now the only tune on the tuner is the new tune sent on the sct. the stock tune is now the new tune too. i have no guages, and lights still on in dash. oh boy. this could be a big problem i am thinking. sent a message to sean. hopefully he can help me out. this is not looking good.
but besides that, truck is running way better.lol
if sean cannt figure it out, might be looking at something like this too.
