what to do next
1-gears
2-UD pulley(s)
3-Cutout
4-p&p tb
5-tb bypass
6-tb bump stop
EDIT: sorry for some reason it won't link directly to the right page, Click on Install Documents, on left side, then scroll down and Click on Throttle Body Bump Stop Mod.
Basically the throttle body blade doesn't open all the way to a 90* angle. you have to grind the bump stop down.
