Map1 seems OK, although the WG spring seems really tight. Then on map8 WGDC goes up slightly and boost goes out of control. Maybe solenoid plumbed in backwards?

Just look at it carefully and evaluate. Solenoid output has numbers, etc.

Ok terry
This was the outcome
Seems to be solved thanks to you
But i think it needs a few WOT's to adapt more


by looking at the log attached and its settings
Is there anything that needs to be adjusted?

Thanks Terry

Looks solid to me! Now it's just a matter of figuring out how much you want to push the setup.
