Hi all, just a quick note to tell you I have finally got around to having the Dawes and Needle valves fitted. Have kept stock boost level (15psi) which my stock patrol would only ever reach 14 no matter what the revs ?? The needle valve has been set to give a slightly quicker boost actuation. What a difference .. much smoother/powerful at lower RPM and more power on hilly sections where I live. Egt is fine as well .... to all those who havent done this mod yet (or am I the last), then I do encourage you to get it done. Had mine done at Southwest Mechanical and Offroad, Bunbury WA ...
