pressure hold on high rpms quick question my cars is chipped with apr 93 software, and i would like to know if anybody has problems loosing boost on high rpms.
my car can hold the boost for a while like 10-15psi but once i go faster it starts to slowly drop psi , the thing is i'll be revving at 5000rpm and my boost will stay at 10psi. In low rpms i can boost up to 18 psi, sometimes it'll spike to 21 psi once i go faster . does this mean more RPM less Boost?, In 4th gear ill push the pedal all the way and boost 18psi, then the higher rpms the boost starts to slowly decrease until 10psi at 6000rpm.
anybody know why? Thanks |
