look at it like this if you are in heavy traffic you want eco tune if you live in the country you want perf tune. or you can use the manual and shift down when off roading or use the hold in 3rd gear. these trucks are amazing.
exactly, and if thats the case then why even use a econ tune? just manual shift in city like how the econ tune shifts and blamo, thats how I use my 91 perf tune.
cause yep as u said, these trucks ARE AMAZING
