People have made over 800whp on the stock unported 1G 60mm DSM throttle body and Honda guys do it too with similar sized stock Honda throttle bodies. I have only done any back to back throttle body testing on NA cars and it usually does nothing on them except hurt mid range power. Kind of a hard to guess part as to what size you need and when one becomes a power restriction. Around 58-62mm usually matches well with 2.5" intercooler piping. I have been impressed with the Boomba stuff as far as idle control actually working. I ran the big, cheap and durable Q45 Tb on my 2G. It's progressive throttle body, so it wasn't just on and off like most big Mustang throttle bodies, but it lacks much provision for idle control.
