I haven't pushed my X2 past level one (25 horse). What setting is giving the best milage? Downloading the milage tune? I have heard that many programmers/chips give the best milage maxed out on horsepower... what do you think?
I love the x2 race. I have never had egt problems with mine. As with any other box if you would turn the box up and hook on to a heavy load im sure it will give you issues. I have crossed the scales with a load of hay at 24000lbs and this box was on the truck at that time. I keep it turned down to level 3 and off I went. keep an eye out the classifieds have em pretty often for a good price.
