I had a customer with a 2006 6.0 just got it back from the Ford dealership for a antifreeze leak and a few other things and oh yes they flashed the pcm . Customer returned his truck back to stock(diablo predator) properly,when he got his truck back he reinstalled his programmer and NO POWER maby a little but not at all like it was before his visit,turns out with this new flash they restrict injector open time somehow, you can watch it with a scan tool fuel pressure is commanded but injectors dont open enough or so it seems we tried different proagamers before he went back to ford and then they told him the truth that Ford is doing this for warranty claims. Does anybody know if there is a reflash for these to put them back? Diablo knows of this problem and are trying to get around it and Ford will not help him at all they wont even try to flash it back to an older file, any help would be appreciated .
