I am running a 155 intercooled Boondocker turbo pro this year and it's worth the price to be with the stock skid. I rode a pumpgas 8lb turbo with a stock skid and even at that horse power it would have seriously benefitted with ARC. I am still not sold on the 3" honestly. At first I thought it was the best thing going, and on a Carls Cycle 900 it does seem to make a pretty good difference, but the turbo's spin the track so fast the 2.5 seems pretty close most of the time. One buddy of mine is actually taking his 3" off his turbo this season. We only had one problem with the ARC cable on one machine, and that was an anomaly. The sled came down sideways on a small diameter stump that went up into the suspension and kinked the cable. Good thing is even without the cable you can just adjust it right back like stock and rock on until you get it fixed.
