The factory throttle body is ~2mm smaller than the hole in the intake manifold. Unless you port the manifold as well, the throttle body is a big, fat waste of money. 4 years ago we took a factory throttle body and bored it out, cut a new throttle plate, and popped it on out 2006. It didn't make ANY difference on the dyno. Zero. In fact all we DID get from it was a P2106 Throttle Body DTC about every 4th time we started the truck. Major disappointment.
If you haven't already purchased it, I would save my money.

Bring back  Windows™ XP and 7. 
Windows™ Vista and Windows™ 8 is a pain in my a$$! 
Windows™ 10 is only slightly less annoying! 
Windows™ 11 is garbage! 
Much to my surprise, I'm actually quite enjoying Linux!
