I am working a 2500 1997 chevy truck converted from diesel to gas.
Today looking for an xdf file for operating system 12212156. I may have it already. but need it tonight.
I need read more from this site and a couple others. Great learning information. I spent most of the last holidays reading and learning about tuning and pcms.
Hello,
Try this one but I think there are better, more richly featured 2156 XDF files out there.
