first off big thanks to guys at goodwin performance. brought my sled up there today and they clutched it for me. hopefully tomorrow i get to test everything out. but while i was talking to them he told me i cold take the shelf out of my air box and it will give it better air flow. but what i forgot to ask was if i would need to rejet for that. anyone have any suggestions on if its worth it or not to do and what jetting i would have to change to if any at all?
