should my boost gauge drop to 0 when i shift?
for some reason whenever i shift, my boost gauge doesn't fall to 0 like i normally see on operating boost gauges. what could cause this?

Re: should my boost gauge drop to 0 when i shift?
When you shift you let off the throttle which closes the throttle plate and doesn't allow boost to pass the throttle body. Its normal. Unless you power shift.

where you have the line hooked up at???????
Should drop to 20 in/mg vacuum when you shift...... |

yes, teh lack of boost is normal when shifting. It goes right back up when you floor it again.

Re: should my boost gauge drop to 0 when i shift?
like I said, depends on where the gauge is hooked up at...........
Mine is AFTER the throttle body, connected to the FPR line, 20-22 in/mg vacuum |

its called a functioning blow off valve draining the system of pressure so as to not cause surging. 8)

For best performance use a bov non recirculated, sending the same air thru the turbo again heats it up more than the ambient air and thus a small decrease in performance. The bov also lets the turbo keep spinning no-load in between shifts reducing lag, if there was no bov, the sharp pressure increase when you snap the throttle shut will slow the turbo right down like crazy, or actually stall the wheel and somtimes reverse it momentarily... that is surge
