GN was running great, got my settings in the TT dialed back in after having to do the emissions test yesterday. Got on it pretty hard taking my friend a set of plug wires. Showed 0.8° of knock on the 2-3 shift. Stopped at a light, and pulling away it showed knock on scanmaster. So, far I've narrowed it down to something in #6. Pulled valvecover and rockers move like they should, no excessive play in the pushrods. Plug looked fine.

That TR6 works great though! I was running 22/23# with fresh plugs gapped at .033"! With the stock ign system I had to have them gapped at .026" to keep from blowing them out.
