Has anyone tried using 03-04 pistions and injector combo in a 2004.5 and newer motor? Keep in mind we want to keep the fueling of the 2004.5 and newer ECM. Seems like the older pistons are more durable.

you have to run the 03-04 pistons with the 03-04 tips. and 04.5-07 pistons with 04.5-07 tips.
'03-04 - 143° - green
'04.5-07 - 124° - red
04.5 piston that had both 03-04 and 04.5-07 tips ran on it.
I'm running 03 style pistons and injectors with an 04.5 ECM.
I ran a recovery program to run the 03 programming, but I'd have to rewire the TPS and ECT circuits to make it work.
for now I'm running 04.5 programming. The truck makes good power, and gets 18mpg. I don't have any complaints with the setup.

possibly a blown headgasket right there.
I havent had any bottem end problems with my swap. 03-04 pistons and sticks and 06 ecm.
