Message After 30" of MP pressure the turbo sometimes goes to 40-46", but suddenly the MAP jumps to 50-60. It happened today also? 
Another thing my engine is running very lean at high MAP with the mixture knob all the way  rich? My exhaust inside changed from being wet black to almost shiny clean.  
 
Hi Buly,
 
Let me be the first to point out that the best way to blow your engine is to run lean under boost.  You should never run this lean under boost, particularly if you're having uncommanded jumps to high boost.  Danger, danger....
 
If mode 1, or mode 9 can't get you the fuel you need at higher map, then yes, you'll need to raise mode 3, which will add fuel across the whole MAP range. 
 
As for the email delay, I noticed that you and John have both had some delays.  Gmail is working fine, but it's annoying to have to resort to such a solution.  
 
Cheers,
Rusty
