Well its a thread in type. Would the size of the hole be the outside diameter of the piece that screws in? And then the tap be the same size as the drill bit or just a bit bigger?

Get as much of the metal shavings as you can out of the manifold. Use grease on the tap and drill, it will help hold onto the metal chips. Your turbo will thank you.

Ok, i was thinkin that i would just turn the tuner off and just spin the motor over so that the tubo doesnt spool much, would that be better than just starting the truck?

fox, my suggestion is no grease on the drill or tap. Point your hole downward and leave the drill and tap dry, 98% or better of the shavings will fall to the ground. The grease will just trap them on the drill or tap and make life harder for you. Also remember when tapping to go in 1/2 turn and back out 1/4 turn to break the shavings loose and let them fall out. Not saying cuda is wrong, just not how I prefer to do it.

I just did mine last night and into this morning... and that wasnt the size i used.
Mine was 1/4 NPT, and i started with a very small bit, vacuumed, drilled 11/32" (for 1/4" tap) vacuumed, tapped w/ 1/4-27 NPT ,vacuumed, then used a magnet to get out the rest. it threaded right in, no problem.
Jim, why is it a prob. if you thread all the way through?
because i did... 
P.S. writeup soon to come...

Mine was 1/8 NPT, and i started with a very small bit, vacuumed, drilled 11/32" (for 1/8" tap) vacuumed, tapped w/ 1/8-27 NPT ,vacuumed, then used a magnet to get out the rest. it threaded right in, no problem.

Yours has to be 1/8NPT rather than 1/4NPT

Actually, i think i remember it being 1/8 npt but it was 1/4" or so in diameter, so maybe that's where i'm getting mixed up.
I have CRS right now. finished gauges at 2 AM, woke up for class at 6. bleh.
I had a friend rev my truck a little while i watched the probe... it's tight w/ no leaks. either i'm lucky or ???
