d5hof

hi guys, i have a wrx sti bugeye, the boost wont go higher the 0.6bar, sometimes it would reach 1.5bar but thats rarely, it acts as if it has a mind of its own. i have a control panel attached (sti genome)(sorry bout my technical knowledge) which has play/rec button, peak/reset button, up/>> button, on/<< button and select button.
any help would be appreciated
