hey guys, hoping you wouldn't mind helping me out with this... my boost needle sometimes shakes violently under boost, and my car always (moreso lately] boosts to somewhere near where it should, and then slowly loses boost pressure. I want to get a boost machine, new turbo lines, and a new DV... oh, also bamm and 4.0 FPR.

I've got an intake and chip, exhaust/dp/cat bypass

help pls!!!! thanks again

 

The needle will shake a little, normally, but you may want to double check the fitment of the lines from the gauge to the FPR.

What do you mean you have a cat bypass. Are you just using a testpipe?

 

make sure all your connections are good....

also, your boost should also start to slowly tail off once you get to a certain point in the rpm range...

 

check the T on your gauge line... make sure the end with the little amber part is connected to the black hose originalygoing into the FPR, (you probably already knew that though)... if you have it set up like that..if not, i have no idea.
