Congrats to NOLA for getting his wastegate setup properly for stage 2 today! He has joined the the 8.0-8.2 psi club with me and the official Prodigy website claim of 8.2 psi: https://www.prodigyperformance.com/3...ler-turbo-kit/

Snarf - I'm starting to think your 9 psi is an indication of a problem. Here's some things to check for:

Leaks in the boost sensing line for the wastegate (along with any other vacuum hoses that it is teed into). Any leak, anywhere in that system of hoses that all hooks into the same small port on the intake manifold, could cause a false low pressure reading to the wastegate, which would allow higher than intended boost levels in the manifold.
Check for any cracks/damage to the hoses.
Check the ends of all hoses for damage, make sure they are pushed on the hose fittings fully, and securely zip-tied.
Also check the banjo bolt for the barbed hose fitting on the wastegate to make sure it is tight.

The evidence seems to be stacking up in favor of 8.2 psi being the true expected boost level of stage 2. I was told, however, that the tune is designed to handle up to 9.2 psi. I think I'll ask for Prodigy's opinion on using a manual boost controller to get the full 9.2 psi boost: http://www.grimmspeed.com/manual-boost-controller/
