Took it out again just now and the wastegate didn't even open in first and I hit fuel cut (which is set at about 25psi relative). So, I'll be stepping down spring weight, but I'm not sure how low I should go? I also had a couple questions about the wastegate installation. You guys have my number, so if one of you would give me a call that would be awesome.

I'm assuming I have an leak somewhere because the turbo takes til about 5k to hit full boost now, and seems to taper of pretty quickly. I know the headers will make me lose spool, but deleting the TGV assemblies and running the EWG should have nullified that loss... Hopefully it just needs to be tuned.
I read somewhere that the spring rate sounds be 75% of peak boost?
