okay, i turned up my boost today and while getting the feel (and a woody:love ) for 15-16psi, i notcied my needle bounces a handfull of times between 13-15psi, but then settle down and holds still at about 15. Why?

boost leak somewhere. try the BOV first. i had to add some washers to my rfl.

Hole in line running to boost gauge for me. :P

an electronic boost controller that's slightly off can also do this. do you have a manual one or an electronic one?

i have the greddy profec B spec II.

if it was a hole in the line or a leak, why would it only do it at 13-15psi and then hold steady out? or for that matter why would it NOT do it in low boost (7psi)?

Good question but mine did it only between 7-9...no where else. Replacing the line worked for me. :P
