If you get a 80mm MAF you don't "need" to do or get anything to make up for the larger MAf.
Not all true. It depends on which MAF you get. With some MAF's, your car won't run properly without a chip telling the computer you've added a larger MAF. You may even lose power if this is so. Some MAF's have already compensated for this by using a different size inlet tube so the right amount of air gets to the sensor. It all depends.
You are right that you don't need to change the throttle body with a MAF change though.
Get a larger TB or something that'll help the flow better than a MAF in a N/A car
Now the Yamaha is a different engine, but I'd guess the same concepts apply to both it and the Duratec. On SHOForum, most everyone (okay, not everyone, but most people with mods) have an upgraded MAF, yet not many have the 69mm TB. According to Yamaha V6, and I'm going to take his word on it, the throttle body upgrade is not worth the money, and it's only $119 in the first place. Cheap in the SHO mod world. Keep in mind that he has done just about every mod conceivable to his Super SHO, including FI. If he has an upgraded MAF, and not a bored TB, I think I'll stick with the MAF as being my choice of the two.
Oh and D-Man, I don't know if the 'tec TB is the same as the SHOs, but if they are, there is a group buy going on at SHOForum right now, if it hasn't ended yet.
