i recently turned boost up to 15 psi and the boost gauge flutters between 13-16 wont stay still?

i have a 7.5 lbs spring is it running out? or do i have a boost leak? has anyone ever had this problem?

thanks

 

sounds like your boosting too much on that spring.. your gonna need a stiffer spring

 

i was kinda thinking the same but i have never ran a wg spring out before so dont know what happens?

just get a 12 psi spring or something like that and that flutter should go away

 

just wondering if anyone here has had this problem


thanks

 

The fluttering is boost going back into the compressor....it happens when you have the bov adjusted to tight

 

My bad i thought you meant it fluttered when you let off the gas...definitely sounds like you need a stronger spring or adjust the spring tighter. you are boosting above the limit of the bov

 

i mean wg spring, when we had it on the dyno i messed with the bov adjester and the problem didnt seem to change, maybe i should adjust it more

 

I don't know if this is 100% true or not, someone told me this could be caused by the wastegate bolts not being tight. Worth a shot.

 

thanks i will check to make sure everything is tight
