Now everyone is going to shim their wastegates down and disconnect the
WGFV :)   Clearly your car is doing fine at 22 - 23psi without
detonation.  Which doesn't make much sense to me.  How can our 9.3 : 1
compression engine not detonate at 22 - 23 psi on pump gas.  What fuel
do you use in Dk?   I am forced to run 91 octane with 10 - 15% ethanol
here in Colorado.  Do you know if your cut off was due to your MAF
signal maxing out?
