Umm I don't believe I was wrong. I wasn't talking about the throttle body in my last post. I was just talking about the exhaust. When I mentioned the northstar I didn't want to switch to a bigger TB cuz I didn't wanna mess with tuning it and messing around with the maf. It's just too much of a hassle for me. I just wanted to take that stupid hump out. I mean some of the things they thought of on this engine I don't understand. But then again they weren't going for more power. Also on another note, every engine needs some back pressure. You can't just open everything up and expect huge hp gains. Thats what I meant about bigger isn't always better. Scooby snacks.
