This is my first time porting a throttle body myself and it turned out great. I didn't think it would make a difference on a mostly stock 5.3 as the throttle body is not really a restriction yet. As I get the truck ready for LS Fest West I'm excited about the changes that are coming quickly. I need to get this thing ready for the scheduled dyno tune.
