somebody let me know if they've had any trouble with one. I've had mine since april this year and it's worked fine but today my car started back firing and sputtering when accelerating. I thought I just got some bad fuel so I tried adjusting the wga and it made it worse. So I put the stock wga back on and the car drives fine, just alot slower. Do these things go bad?

 

its possible. What is your boost when sputtering? Is it spark blow out?

 

It jumps around 12 to 8

 

check your spark plugs..its mostly likely them..

 

Alright so I got bored this afternoon so backed the pretensioner all the way out and reinstalled the apg wga and now its running perfect WTF!

 

Well I'm going to go on a limb and say that you had a vacuum leak somewhere. I've only seen 2 reasons for mad boost flutter:
1. ignition issues
2. Vac hose leaking.

 

It must of been, but I checked all the lines and they seemed fine and the plugs are good my car has 5500 miles on it maybe I need a boost leak detector.
