has anyone done data logging on the N/A to see if RP's numbers of 59-63% duty cycle on n/a injectors is true?

[B]No. It's the fact that the injectors are turning on that causes the hesitation, not when they turn on. There are ways of fixing that anyway.

lolyea it would be cool to be able to get an S5 AFM on the S4 or just something bigger

I'd be interested to find out when the AFM actually does max out. I recall some guys hitting upper 200 rwhp's with the SAFC, and the air flow was reading in the upper 90's. If the ecu was reprogrammed for 720cc injectors, and the timing was tweaked a bit it would be a slick set up for a bunch of guys running hybrids with the basic bolt ons.

I read somewhere (or maybe i dreamed it) that an S5 AFM was capable of 550-600 cfm and the S4 was no better or worse. Not enough flow to make any power, especially for something that breathes like a big block. I think a conversion to a gm corvette MAS would make a huge differance. Wonder how complicated it would be.

wishing someone would help out the poor and make the stock system not suck.

With that said and done, what makes your Anti-flood any differnet than anything stock?
