This is the biggest reason I decided to get the tune. Northern Michigan speed limit is 75 and on mild hills, the transmission is completely at a loss. I knew it would only be worse pulling a 3-4k lb boat.
Got back last night from the UP of Michigan. Was there since last Wednesday for the Yooper Side by Side Shotgun Classic shoot. 734 miles round trip and no 75 mph speed limit along the way, the path from here is across the Chequamegon-Nicolet National Forest in Wi. Those that lived in downstate Mi. and East, Ohio and Indiana, left after the awards banquet on Saturday night. The Mackinac Bridge crossing on Sunday's they all said is a 2-4 hour wait due to road construction.
I tow my Ranger Northstar around 3K pounds just a bit over often including this trip. Speed limit in South Dakota is 80 and when towing I keep it ~75 mph, same as I do on most Interstates around here which is 70. With a trailer things can happen really fast above that or even below and nothing good comes out of a blown trailer tire. I don't skimp on trailer tires.
First thing I do on my new Polaris Rangers is take them to Terry Gilomen in Northfield, Mn. for his ECU tune. People send him their ECU's from all around the world but I drive an hour and drop the buggy off for a couple of days and let him play with the clutching and beef it up, also go with a low RPM tune. Takes it from 82 hp to over 100 hp plus many other changes. Worth every penny it turns it into a beast.
Not totally convinced on the GX yet hey I'm watching you LOL. 11 years with a Taco the shifting in the GX is much improved especially in CC and towing. Compared to a Taco and FJ at least.
Not a lot of billboards in the UP but this one caught my eye and had to stop and take a picture
He wants $600 for 19+ GX 460's.
