ok i have a locked dizzy for my turbo app. 12a setup. 10l 10trailing behind leading. Car makes like a ping noise or something at idle goes away once reved. its kinda weird it almost sounds like some sort of compressor surge like some thing is slapping the turbine but it worrys me as to why it would do this at idle. never did this till i locked dizzy. So i am wondering if it maybe needs to be slightly richer at idle since the timeing is advanced 10 degrees at idle now like i said once i blip the throttle it apears to go away.

Searching now but help if you can!
