It DOES make a difference as Hooch and Nick will testify!
oh yes, a hell of a difference, but it's not good for the life of your turbo!! with a forge actuator, my K03s was spiking at 27psi, that's the LOWEST jabba could get it to spike at when they mapped it. it was holding 16-17psi aswell then eventually dropping to 11-12psi by the redline. it did however go bang after a couple of months.
