Hi all finally signed up, I’ve been using the forum for tech info for years but figured about time I sign up. Recently put a new engine in my 09 gmc, 5.3l shorty headers, cold air kit, cat back, stage 2 cam I am looking to upgrade the throttle body to a 90-100mm the truck is heavy and need more pull. Which throttle body will plug into the factory wiring is the 6.0-6.2l a bigger throttle body with the correct plug. Any help on this would be appreciated. Thanks in advance
