No consistent regulation of boost
When first installed this 12psi spring only held 10. As time when on it held less and fluctuated even between gears. Not a very solid wastegate spring

Did it's job
Did exacally what I needed it to and stopped my wastegate flutter under boost beyond my old springs capability. The thing was pretty tough to put in because it has so much tension.

Spring pound rating is not accurate at all.
Not at all an 9lb spring. I put this in my 38mm wastegate and ran just off of spring pressure and it made 18psi. That's a 2 good difference in pressure versus what is advertised. Total waste if time and money. Stay away from these and this liar of a seller.

Boost your heart out of your chest!
It boosted hard. I think it wore down my journal bearing turbine. Maybe blew out some oil seals. I don't know yet, haven't disassembled the turbine. It definitely worked though, I would recommend buying this spring if you want to boost your turbine hard.

Not the right size
Ordered a 15 psi spring and upon driving it on the road without even having a boost controller hooked up it made 32psi. I was clearly sent either a defect spring or the incorrect size. Very disappointed.

Not a 15psi spring!
Damn near roasted my engine. Installed and spiked my boost to 25 psi. Spend the extra few bucks on the real deal replacement springs.
