I can certainly find/dump a stock 4.8 or 5.3 (or whatever) tune. Which cam is in each car? Stock GM truck?
5.3 from a 2001 GMC Yukon (drive by cable)
5.3 from a 2004 Chevy Silverado 2500 (drive by wire)

Ok - those will be the same tune, other than ETB stuff (which isn't really useful to us anyway). I know I certainly have the VE/ignition tables from that engine handy, since mine is a 2002-ish 5.3 flex fuel van engine (LM7/L59/LM4/L33 all have the same VE table). I'll have to see if I can export the table in some sort of useful format. Worst case, hand entering enough values by hand and using the interpolation button will get the engine running acceptably.
