or so i was told, i have had this programmer in 1 truck for over 4 years, 03 gmc 2500hd dmax, i traded for an 07.5 a couple months ago and the night before i drove from savannah tn to louisville ky i returned the 03 back to stock to try and sell this programmer, i work on a towboat and am away right ...

and im wondering if i can reprogram my diablo predator that is designed for the 2003 duramax to one that would program the 2007.5 duramax, they are the same number u7136 ithink

ok i got home and plugged it up and it IS revision 1.11. would there be any problems with the programmer that could be causing my weak shifting tranny, i took it out and now it seems to be shifting firmer than with it installed?????

i can print out a page off of paypal that shows dealer name and email and paypal name,auction # , and also what I purchased, but evidently , they have gone out of business, I have tried calling and emailing with no luck, will the paypal reciept be enough to get my programmer revised to the latest ...

but , are there any other ways I can tell which revision mine has. I bought this off ebay about 1 yr ago and it seems like the transmission slips slighty through every gear change. I mentioned this to a dealer in tupelo Ms and he said it needs to be revised but he wouldnt do it or send it in for me ...
