Missed your post winfred - yo you need to check out megalogviewer - you auto tune your cruise map and load your WOT region a little richer than you anticipate needing. Datalog, and send the log file and the MSQ setup file through MegaLogViewer, it uses a "VE Analyzer" and tunes your whole map to match up with your target AFR table! Its very very very cool and works very well. I had my fueling down in about 45 mins using this method.
Anyway, update time!
The pistons are now ceramic coated with TechLine Cerakote CBC1 coating - was fairly painless, though
getting it to spray through one of various guns was a challenge. One piston was either not aluminum oxide
blasted enough or had some oil still on it, and it had a small spot that bubbled, and is going to be re-coated.
Otherwise, they came out real well!
They had a slight little "lip" to the finish since they were masked then sprayed. Using a yellow scotchguard pad, the lip is
easily removed with very little rubbing (it isn't bonded to metal so it moves from the object).
Here is a pic with slight lip:
All cleaned up:
