[QUOTE="sonic blue l, post: 1214582, member: 5185"] alberta, about an hour from Edmonton. You? I went to bc last summer up and down the coke. it pulled great, just would over rev on steep down grades. Then truck would not shift back up right away. So i'd have to turn tow/haul off then back on after it shifted up. I've read on the mcc portion that someone was complaining that their truck would rev to 4,000 on acceleration with tow/haul on h&s default tune. I never put my truck to wot when in tow/haul so im not sure if it would do that as well. I never did read a conclusion as he was trying to get mcc to change the shift points, but as far as I read it never worked. I think the over rev issue will only occur during aggressive engine braking, as I never had a problem while in alberta. [/QUOTE]
