Newbie needs mod help (please help)
I just bought my first diesel. It is a 1997 F-250 PSD Supercab Long Bed.
My main goal is to increase fuel economy as much as possible.
I plan on starting with tymar intake and either straight stock pipe or 4" exhaust. I found a tuner in the back of the truck and have no idea how to use it, nor does the dealer that sold me the truck. I am worried that any mods I may do might mess things up.
How do I know if my truck is set to factory settings?
Do I need gauges when I do the Intake/Muffler mods?
I will found out the name of the Tuner and try to send some pictures.
