I have read they have trouble reading the multiple sparks of a msd box, but all i have is the msd street fire hei. I also used a stock gm hei off of like a 85 chevy truck or something like that with the same results.

With the dial back lights, I set them on 0 and used the tape I put on the balancer and I set it to 60 and got the same thing. I think actually what i'm running now is 56 at idle with vac unhooked and plugged. My uncle has a regular non dial light that i am going to borrow next weekend. I just don't see 3 lights all being off that far and by the same amount.
