I'm considering a "mild" box for 03. 5 48re 4x4 quad cab 3. 73's for better performance and fuel economy (if such a thing exists).
I do not want to be my own warranty shop nor do I want to stack boxes, blow up my trans, throw codes, change injectors, fuel pump, exhaust at this point in time (only 23k miles on it). I will add gauges as anyone should who adds a performance box.
Seems that many readers have done extensive upgrades to reach their goals. I've never had a fueling box and wonder if "mild" means I'll hardly notice? In that case it would be questionable, considering potential warranty penalties.
Please try to voice opinions based on experience not company affiliation.
Thanks guys!
