Just picked up a brand new 2011 extended cab 2wd silverado with 3.73 gears. The thing was a dog with the stock tuning. Just did minor changes that woke the truck up tremendously and still very safe. Still has 50% torque management at wot.
The 1-2 shift has slight wheel spin it is not harsh at all i think its the tires cause even from a roll this thing will blow the tires off in 1st. Let me know what you guys think and if you have any suggestions.
