I have read the Tuning Basics by Mike Dorsey - great information there. But it's only a start. I want to create an economy tune for daily driving (a lower priority) and tow tune for hauling my horses. So with respect to the Timing, Duration, and Pressure tables that Mike points to,which direction do I start heading for those two types of tune?
To be honest I don't drive the truck very much anymore (less than 5000 KM in the last year) so the "try it and see" would take an awfully long time to verify consistent improvements in economy and also why that tune is a lower priority.
