No thanks, stick it on parts for sale, i'm sure it'll go.
To tune it I kept turning the pressure up until no knock. Leave it set there and run it until the low pressure light comes on.
I've got the IPO kit for ~ 6 months now and just filled up for the second time. Cost, I think, $3 something.
Spent a couple hundred, no transition knock, goes fast.
Works for me.
