dont bother getting the hand controller, save your money, once rms has tuned the car you shouldnt need to touch anything on the hand controller, rms will tell you this also. And it is a good idea also to keep the greddy ebc, its better having an external boost controller, alternating between a high and low setting, this can be incorporated in the tune of the link however you wanna put it. Keep the ebc, have a high and low setting, say 11psi and high on 17psi. Then that controls ya boost, as i said dont bother with the hand controller waste of cash and you dont accidently wanna stuff any of the settings rms has put. Alternating between a high and low setting on the tuned ecu will be fine.

i had a link on my white wrx, didnt have a prob with it, i had a the antilag function on it, if you really after antilag for wank factor, dont get the link, antilag on the link doesnt coz big poppage and flames. But if your not worried bout antilag i recomend the link.
