I purchased a turbo kit a few years ago and it came with a evolution wastegate. It appears the install sheet I got differs from the one you have poster here on the site. I assumed I had the 5 lb spring in when in fact it was the 9 lb. I swapped out the gauge because I thought it was defective then I just assumed it was boost creep. Now I'm needing to replace my tranny due to too much boost. Sucks to be me.
