Under boost it will shoot up to 50 depending.

Also depends on the climate and elevation where you are at. But, being from Chicago, most people were telling me, by the way, I'm running a Kenne Bell, but it makes no difference, but most people were saying at Idle 42psi was good. I have it just below and it's running lean until I give it gas. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Wolf</b> <br /><small>Member # 1723</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,7,23,6,44,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I'm running 40psi with the vacuum line disconnected, then the AFPR increases FP 1psi per pound of boost.
