I've been looking to improve the shift performance of the tranny particularily the responsiveness to a downshift when accelerating for,say, a hill or passing, now I have to almost floor it and its slow to shift down. The Hypertech talks about improving shift hardness and shift points but but I can't find anything about the downshift. Anyone here got a hypertech that can comment on the tranny shift qualities both up and down the gears? I like the hypertech because it lets you restore the Factory settings. 2007 Avalanche LTZ 5.3. Thx
