Hands itchy and I twisted the manual boost controller (MBC).....

As the title says, I did it and opps, nothing happened.....

I even turned the knob to the end on both ends and alas nothing happened.....

Then I noticed the previous owner has routed the vacuum hoses like the stock setup.....meaning going though the solenoid before going to the internal wastegate actuator.....

So, I did a direct connection between the MBC and actuator.....


The result is a scary one where the actuator did not work and boost went up to 1.0bar.....

This is how it looks like before and also now after rerouting it back.....

Was so worried and promptly reroute it back and maybe a EBC is on the way?
