Hot Idle seems a little better. No big surge when put in gear. Small surge is there at times. Sometimes when I start the car while it’s hot after it sits for an hour, the idle searches about 80 rpm up and down for a minute or so. *ALSO My Turbosmart plumb back diverter valve was defective and for some reason they sent me the Turbosmart Dual port diverter valve that recirculates 1/2 air and 1/2 gets vented to atmosphere. Not sure if this changes your tuning?
