HKS 40mm External Wastegate

[Spooling]

I have an HKS 40mm External Wastegate and I forgot the spring tension / boost rating for the spring installed in the gate. I could have sworn I kept that literature - yet I looked everywhere for it and I can't locate this info.

The spare spring I have in my garage on the shelf is Purple in color and the one presently installed in the gate - *I believe* is Blue.

I bought this thing many years ago from Mike Modern Musclecar.

Many Thanks !!!
