Maybe he can cancel a remote location journey to pay and get the truck running? Just one trip at 8 mpg tops would pay for the tune day with me...
You won't find much to be had from a 4lo tune espeasilly this ECM, I can't even see a dyno work in 4lo with 46 inch tires or a dyno owner trying? Those tires would only need 20PSI for the street, drop them down to 10 for a load on data.
