So i have a 03 4.8 silverado, recently installed a cam, heads, headers, torque converter, cai, and exhaust. I ended up having someone tune it, but truck keeps turning off on the idle, not only that but i feel like the truck wants to let the power out but it restricts some of it. I feel like the kick should be felt more especially becuase of the converter but nonetheless at this point im wondering if its the tune or something else.

PS Any info on BLACKBEAR TUNE or any others would be appreciated.

 

where do you live?

 

I live in Los Angeles, CA
