1. Before I actually post the file (In case its against the rules or something), is anyone on here able to convert an hptuners file (from my friends truck), over to EFILive file for a starting place for my newly swapped 6.0 lq9 in place of the current 5.3?

2. If that isn't doable, would it be possible for him to upload that tune, from a 2004 dbw silverado ecu, into my 2002 dbc silverado ecu? And me just extract it from my own computer after that?

Any help or suggestions would be great.

Thank you

Jeremy
