i got a question on setting the desired boost for hi and lo....but....its in percentage. now...we did the switchover on one where the unit displays psi instead instead of KpA(bar)...and when we go to set boost...it shows the psi version instead of percentage....am i on crack or is this what i am seeing cause the number displayed it the psi that comes up on the autometer guage. can we set it off that....instead of the whole percentage thing.
