2005 ext 5.3L Performance programmer
Does anyone know where I can get my ecu programed? I bought the new programmer from Diablo after talking to them on the phone and it did not work on my truck. I called them and they said that it only works on the 06-09 which is not what they told me when I first called them. So I sent it back and got a refund. All the major program companies that I've talked to said they don't have one for a 05 5.3L. I need to adjust for 4.10 gears, the 32 inch tires and turn off the stupid d.o.d.
