I have an 01 Ex. and a Predator for it. I do not have power to my OBD II. Is it still possible to re-install my factory backup without having power to the OBDII and use my wall power supply to power it up? Or will it not talk to the truck because it is not powered by the OBDII?

I have a customer that has the U7165 for their company van. They took the tuner out when they took it into the dealer for work, then went to put it back in and the dealer had updated the ECM, and so when they went to put the tuner back in it showed vehicle not in database and the cal ID was VXCF7A3 ...

I have three other U7170's that I bought and had the faulty more recent program on them with only the tow, 80 and 110 hp settings. I replaced the faulty program with what ...

Has anyone had any feedback from customers about the Extreme PowerPuck on ie. the duramaxes, CAT, International engines? I want to start selling them, but it's hard to get a first customer interested with no feedback. At least something other than"it supposed to..." I appreciate any help.

What was the fix?

What is the max recommended towing weight of a trailer on the tow mode for 7.3, 6.0, and 6.4 and why

I've had three bad U7170's and DS said they are totally re-doing the program, said they would have it done 'soon', we'll be able to download it offline and hopefully fix most the problems that we've been having with these.
