Jeff - that made complete sense!

Update - I adjusted the wall wetting and immediately it was improved but still seemed like i couldn't find the sweet spot.

So then I changed the fuel method from MAP based to throttle based and bingo! Revs up much cleaner now without the popback. There might be a little popback due to a vac leak on cyl 2 but it isn't that bad. I suspect there is a leak somewhere in my brake boost which is directly hooked to that cylinder. For now, i might just adjust that individual cylinder trim.

GLad that I can put the fear of a botched cam timing issue behind me!

My lord does this engine rev up fast now!
