YOU'RE RIGHT! It's all based on a single hole!
I do LOVE the instantaneous throttle response they deliver!
You crack the throttle - you go zoom zoom... :>)
Talking to a tuner about IR's -- he says that to tune them correctly you have to add cells to the tables - especially down low (high vacuum) because you crack the throttle and there's lots of AIR but no fuel... so he redefines the tables to be able to have the cells (more and closer) to react to that inflow of air. Made sense to me.
I'm not using the correct descriptions for the tuning part - but you get what I mean.
