I agree - the throttle is crisper; no doubt on that. But, ya lost me on the "why" of it,
unless you're throwing CAMS into the mix as well.
More air going through the throttle blades is a function of lower IAC counts...which were likely set after installing bigger cams, yes? And, as for velocity...you'll have to
"splain it Lucy!"
I think the response crispness comes from (according to the FSM) the ~ .4 seconds for the SPT system to fully comply with the "ON" signal, but only in certain situations.
In normal driving i.e., the throttle is opened more or less gradually and the SPTs are activated w/o the driver being conscience of when the .4 second lag interval began. Therefore, the response time isn't relevant (or even noticed?). But! If any time the throttles are snapped to WOT, in anticipation of an immediate and FULL POWER ON response from the motor -
and the quicker the better -
.4 seconds lag seems like an eternity, especially when at the drag strip that guy in the adjacent lane has jumped a car length on ya!
Well, whatever the reason, the crispness IS there (the FSM says so!), and if one has an aluminum FW, the "seat-o-the-pants" meter will definitely agree every time the the throttle is whacked!
