No it doesnt but when I run my picco I tune it by ear and overall feel of the engine more then anything and when I take its temp it says that its 170 I dont get it. I used to run the mip onboard temp guage but they always quit working I went through 3 of them they always seemed accurate. Is there a better diff for the savage xl or do they already have the good diffs? I blew both diffs yesterday lol..... good thing its fall and snow is going to fly right away ill have lots of time to fix them up.
