That the e-boost 2 Sparky ?
Boost control has come a long way with the various electronic controllers now
Another to consider is the AMS-1000
They work differently, so one may suit you more than the other
E-boost presets a pulse width modulation (duty cycle) to a solenoid,
the solenoid can be used in different ways, but the most common with an external wastegate is to divert some of the air used to activate the wastegate and send it to the spring side of the diaphram , this adds to the spring pressure in a controlled manner, the higher the duty cycle the more manifold pressure adding to the spring pressure and more boost
you set it and then test the result for each stage, our bikes run a similar system and some previously were running the E-Boost
10% DC would raise the boost level a couple of psi, and 80% was about the max we used on a 6 psi wastegate spring to get ~28 psi in the plenum
Good thing about the eboost was the dc was not necessarily a set rate through the whole gear , you can tailor the boost curve to ramp up after a gear change and not be a big step at the change, or pull some boost out at the top of the rpm range , all you had to do was understand the instructions.... that was the difficult part
Ams-1000, probably more experianced guys with these than me here .
But basically its reactive, you set a boost level and it aims for it , has 2 solenoids , one to add air and the other to release
