For a rough estimate tune the 7500 and down for your maf tune and for wot do 7650 and up. For the 7500 and down you will need to set up a histrogram if you have hpt that is. If you're trying to do it manually your pissing in the wind. Then once they lock in at 0 at wot you can tune the 7650 and up for wot while watching the o2's.
Just go 01.00 at first to get you in a better state to go WOT. Then just go increasements of 00.30 or decreasements of 00.30 depending on where you need to be at.
When i put my 78mm tb on i was seeing low 500's on the NB. I couldnt figure out what was going on. Took me forever. And belive it or not I was getting no kr also...just 1 or 2 degrees
