I was in the process of finding a proper WG SNS value. The manual  
actually says to find WG SNS based on boost target (page 18):

" A value of WG SNS needs to be found that allows the boost to rise  
up to BOOST TGT without overshooting. If the boost fails to reach  
BOOST TGT, raise WG SNS. If the boost pressure goes past BOOST TGT,  
stop accelerating and lower WG SNS."

Therefore since my first WG SNS value of 44 surpassed the target, I  
dropped it to 42 and lost all boost control activity. Then I raised  
it to 43 and no boost control, and then back to 44 and no boost  
control. Is that not odd? And depower/repowering still shows the  
proper stored values in the ecu.

Or am I not understanding that properly?

I have lots of logs- will get to them on the pc shortly.

thanks, rob
