Adjustible blowoff valve
NO !!
You need blowoff valve that is large flow and open at idle.
On carb models sleds you need to bleed boost off before carb float sense hose or tube.
EFI just needs one at air box to keep good throttle response and not to have sled wanting to run on after letting go of throttle.
Blowoff valves also help the life of turbo and keep turbo from stalling or trying to stop in a split second from 100,000 RPM!
Just my two Canadian cents worth!! But there getting worth more!!
Everyone have fun and when your fingers are frozen and ya gotta take a leak!! It is still small know matter how much boost!

Where do you think is the correct place to monitor boost pressure?

It depends on how big a turbo you plan on running. I use a Turbo XS and it seems to be working great (that is after I cut some coils off the spring so it would open at the least drop in throttle closure).
