so I know that efi live can not be done on 05 and older. My question is sense mine is an 05.5 (build date of 7/2005) if it could be done with an 06 ecm?
You guys have been waiting 10 years...we only agreed a couple of year ago to look at it....surely another 6 months or a year is no big deal. It's all relative really.
I in know way feel like the owe me any thing. Im just saying were last on the list. I would love to have it and if its ever availible I will have it but in the mean time if we want it now we need a Chevy crude or somthing I heard will be released soon for them if not already
actually, 4th gens are last on the list. OP, if your truck has the new style headlights and valve cover then it can be tuned. It if looks like the 03-04 trucks then it cannot be. You can do a standalone 06 ecm and harness, but you will lose your dash functions.
