what kinda advice is that?
because he runs off the actuator, and doesn't get 25psi... he needs to back cut wheels or change housing? lol.
-5s will hold 25psi if they are set there.
running off supplied items, garrett or hks will only ever see 15-16psi, and hence he needs to mod the actuator, get a ebc, or bleed more air off. quite simple really.
