The supercharger gives the transmission more power than its expecting with a stock tune or the unichip. The unichip only controls the air/fuel ratio and it sucks at that btw.Ive been reading around the forum about messed up shift points on a supercharged Ffv because of the uni chip. I cant find a thread dedicated to it though. Does this happen to every one or are there just a couple guys with bad luck?
Yes, there is a TRD re-flash out for the 2013 models. I'll upload the installation manual when I'm at my laptop which shows every supported truck at the end.Thanks BRX. Do you know if the current TRD re-flash would work on a 2013 non-flex fuel or would it need to be a 2012 or prior?
