So I just got done towing around 575 miles to and from Harlan KY over a series of pretty mountainous interstates. I averaged about 8.9 mpg while towing. On the flats it held 75 mph pretty well, but on the uphills it struggled to find a gear and oftentimes would shoot to 5000 rpm to get back to 70 mph.
I've been reading about the plug-in tuners that are supposed to help with horsepower, torque, towing, and the like. I've seen some as low as $79, some as high as $500+, and the Jet Stage 2 tuners around $250.
Is this a gimmick or is there some legitimacy to it. Can anyone give me some input on using a tuner on a 5.7 Commander?
