So I installed the tuner on my kodiak tonight and wow what a difference. First- it started first time no second try, second - the pull on the lower end is much improved. I have a 3500 lb winch a diy rad relocate, 2 ammo cans full of tools on the front rack and on 28 inch cst wildthangs if I would have leaned back and pulled a bit on the bars I could have wheeled no doubt. I only ran it around the yard and driveway, but I am impressed what difference it made, and this is the caned tune that ehs put in for the kodiak. Tomorrow night the wife’s bear gets her tuner.
