Thanks for the replies....

I pulled the plugs and they're nice and tan ....also the compression is fine.

As far as the controller goes, I'm absolutely sure everything is hooked up correctly. I started out tapping the bov line initially because of some of the posts about spiking.....but that didn't make any difference for me. The hole drilling mod seemed to reduce it bigtime (maybe 1psi spike now). I must admit I have a considerable amount of extra vacuum line attached until I decide where I want to mount the controller which could be causing some of the problem.
