Today I was driving my car and it was running great and pulling hard, but then all of a sudden when getting into boost it was bogging down or maybe misfiring. It is an FBO car running E85 with 26k miles on it. I don't think the plugs have ever been changed. Didn't throw any cel lights and runs fine at idle and when driving unless in boost. Anything else I should look at before changing the plugs? Thanks!

Yeah i understand that but it`s the only way of isolating the coil if it is indeed the problem. My guess is still the plug but obviously i can`t be 100% sure.
It`s an hours work to remove and install the manifold so it`s not that bad, that`s if you do it yourself and you have a garage where you can work you don`t even have to replace the gasket so no cost involved.
If your plugs were changed more than about 2-3 years ago and you run corn i still say plug.
