I have a 2006 express 1500 with the 5.3, I am looking to make a little more power when towing. Does anyone know if a throttle body spacer will work off of the same year silverado? 06 is the last year before the express switched to dbw and dant find any info on it

 

Throttle body spacer will not give you more power. In fact it will not do anything but waste your money.
