Bill, if you don't like the idea of using Mode 6 = because=20 it may cause an adjustment of all bins above staging - here is an = alternative=20 suggestion based on the way I coped with the situation.
 
As I mentioned my engine would also bog due to = leaning=20 during the staging process - being too lazy to read the manual and spot = Mode 6=20 as a possible solution, I used the "brute force" method.  I = observed that=20 when my engine staged my bin pointer would jump from the 30 some region = to=20 around 60.  It was immediately after I observed the manifold = pointer to=20 make that jump - that the air/fuel ratio went lean and the engine=20 bogged.
 
So from the lean indication I was getting , I = presume my=20 engine was (for whatever reason) not getting adequate fuel in the bins = around=20 60.  So I started increasing the MAP values in bins 60-65  = higher=20 (enrichen) in incremental steps.  I found that each adjustment = richer in=20 those bins caused the bog to become less severe giving me a comfortable = feeling=20 I was headed in the correct direction.  Eventually the bog = disappeared and=20 my bin values above 65 were not affected because I did nothing to change = those.
 
You might want to try that method - but I would = give Mode=20 6 another try by adjusting below staging and checking results above=20 staging.
