check out this iphone :-) idle clips fyi
dead smooth idle (doesnt even slightly idle hunt) and s/c noise only showing whistle noise :-) your s/c will quieten down slightly for sure :-)
note ; my idle is DIGITALLY smooth, it doesnt even fluctuate slightly..... its far smoother that the stock MAF tune, this was specifically one of the things i was most impressed with, as your only missing the crank pulley, im guessing thats all thats causing your idel issue?? what else can it be, dont be afraid to "sympathetically" use the entire rev range, the car needs to learn fueling EVERYwhere, ;-) im saying beat the hell out of it, im saying just gently push the revs alittle higher and for the ecu to see the higher rev range, you will not be running lean at all ;-)
wait till you get the full boost and proper rev range performance!!! properly fast.
