Well finally installed my boost gauge after a long time. Few questions about the psi. While idle the psi reads 24 below 0. Is that how it is suppose to be or is it suppose to be sitting at 0? I only really got to get on it once since the install and I was in third gear and it held at 14 psi til redline. Is that what it is normally suppose to be at? I'll have to run somemore test when I get some time.
