    you cant lower the boost lower than what the spring is set at. so yes a new srping is the only way.

    The spring is in the wastegate. You're gonna need to educate yourself a little on how turbo systems work before you start playing around with yours.

    dear god, be careful when you open up that wastegate... that spring is under a lot of pressure and when you release the clamp that bitch is gonna pop open faster and harder than paris hilton's legs at a naked barn dance.

    Because I say so.




    Plus the wastegate controls the intake charge pressure.​

    well if the spring is set at 12, then u cant drop it unless u change the spring, but i bet its probably got a 7 or 8 pounder in it and he tuned it up to 12, jus get a boost controller in that case

    is this turbo internal or external wg?
