Yeah, the mud probably helped. But also, Sal, I was wheeling with the ESP entirely functional, this was always killing torque and momentum. Also, last summer my fans would refuse to come on to keep engine and tranny at low temps. Programmer resolved that. It's not a perfect set-up, but its a working one. I would not dream of trying towing someone out, lol - not the way im loaded.
But, of course gears and xcase swap will definitely Improve things A LOT.
