All I can say is WOW!!! I used to have a manual boost controller installed where my peak boost would be at peak RPM...Just installed my Greddy Profec B Spec 11 and I can say is its one of the BEST mods I have ever done...Now I get peak boost (13-14psi) at 4500RPM and hold boost steady until redline...A HUGE seat of the pants dyno difference...It is amazing...!!!!
