Sounds like a bad plug gap. The BKR7E-11 are pre-gapped and cannot be changed. There was recently a thread about plug gaps, I suggest you check it out.

what maf are you running. I had the same problem with my q45 maf and my in and out settings were wrong! AFR is air fuel ratio! If you dont have a wideband you should get one. It will tell you how rich you are!

I run BKR7E-11's. No problem at 18psi.But I also have a MSD Blaster SS coil and Nology plug wires..

It's all dependant on your setup. It's not a global setup. Do what works for you. Gap your plugs small, then go up till you get a hiccup.

I'm drunk, so take this with a grain of salt... or dirt.. or whatever.. bleh
