I went from a 3200 stall to a custom 4800 and some even bigger heads. After retuning it idles steady and drives great except for one little thing. When idling in park or driving slow if I blip the throttle to 2500-3000 rpms the idle dips 350-400 rpms and then recovers. My question is which way and in what area do I need to adjust the throttle follower to get rid of this?
Any input will be greatly appreciated.
It is a 2004 LS1 with a fast 102, 102 tb cable throttle body with 100 mm maf.
