What im doing is I'll entre a duty value of say 20 percent do a pull from 2000 to the limiter log it then in a graph mark down what boost it achieves at what rpm then i will do the same for 30 then 40 and so on till i get to 100 percent duty.
I will then have a table with all the info to make a boost duty table.
But with the boost valve turned off its dropping boost after peaking with duty at 100 percent it peaks around 30 psi and then drops under 20.
Obviously with setting the duty i could hit 20 psi and hold it to red line but it should do more and 20 psi at say 6000rpm would be 100 percent duty.
100 percent duty is pretty much like pulling the pipe of the actuator so there must be a problem
