I need some advice on how best adjust dual efie. I have a digital dual efie I bought on ebay and have installed and tested connection so that I know it is hooked up properly. I have been told a .200 mv increase is a good starting point but I am wondering what everyone else using efies have been using. I am running about .8-1.0 lpm on my smack booster. How do I know when I have increased efie too much etc. I connect my meter straight to digital efie so it is very easy to increase in small units unlike the analog type efie.
