hey yall, just received my tuner about a week or so ago, still have to send in the disclaimer (been working overtime to get my savings back up). I have been reading about TCM problems when flashing or the tuner connection failing during flashing. Some blame TCM, some blame the connection cable. Either way, I'm getting nervous about putting the tuner on. Should I be? Worst come worst, how expensive is a TCM and were there recalls on it? my truck is a 2010 F250 ECLB FX4 with 88,xxx miles and automatic tranny.
