5.2L Performance ideas
 

Hi guys, I have a 97 1500 sport Club with the 5.2L Auto. New to forum so be nice... Besides air flow (intake and exhaust) what can be done to improve mileage performance? I use it on / not off the road although I am riding 285/75s.
Shifts well but seems to go into OD sooner than I like which sucks gas.

Thanks for your ideas.
