the maf is a nice way to go until you max it out; that is not real hard to do with forced induction. At that point tuning becomes "tricking" the computer through the pe tables, and I do not like that at all. I always go speed density with forced inductions, just easier, less to go wrong, and runs just as smooth in my opinion if tuned properly.
On the throttle bodies, every time I've swapped from a 4 bbl style to a monoblade I've picked up throttle response, so now I just start out with monoblades. And 90mm is plenty, I've made well over 800 rwhp with a much smaller 75mm monoblade. Not much of a restriction when under pressure.
