Hello Michael, and welcome to Gadgetmangroove land.
I have a video on YOUTUBE that involves rerouting the IAC to get more performance and more mileage from your explorer.
It is under the title on youtube GadgetmanNebraska1 and it is a service bulletin I did for a 5.0.
This is some fantastic results from the little bit. I can't wait to see how larger bit does for you.
Check thickness of this particular throttle body though, you might have to build up the backside of tb before grooving with the big bit.
Keep up the good work, and if this impresses our wives it will impress anyone,
Great post on your first griive by the way.
