Just got my computer back and installed on the '04 Silverado! Excellent results. Shifts are much improved, no lag just a positive gear change without being harsh. Throttle response much improved, truck is much more "fun" off the line. Downshifts are much improved, no bogging, just a quick gearchange and away you go. And thats just driving "normally". Floor the loud pedal and the tires start looking for traction, truck gets a bit sideways, gear changes start clicking off, and the damed thing sounds like a Corvette on full boil! Very happy, and would recommend BlackBear to anyone. RT

 

Yep, Justin is very good at what he does and has great customer service.

 

I have heard great things about Black Bear.
