It pings under light throttle.Runs fine with it disconnected. But I would like to run it hooked up.Here's my combo, Iron head 360/KB 107 pistons, RPM intake, 234/244-.488/.510 hyd cam,mopar dizzy w/crome box,16/18 inital 34/36 total,160/170 cranking P.S.I., 750 DP, TTI step headers ,2 1/2 full exhaust, 5-speed tremic, 391 gear. Can anybody tell me why I have vacuum @ idel from the port in the metering block? This is where you should hook up,correct? Thanks Mike 4568926-New018.jpg (59 downloads)

EDIT you can insert a 3/32" allen wrench into the vac can to reduce it. Cant remember if CW or CCW reduces it.
