Goran and Brian:
You guys are wizzards! I siliconed the gasket and plate, and bolted the popoff plate down hard. Car now has zero transition problems! The AFR sems quite more linear wrt RPM, doesn't drop to the wretched 10 AFR; actually just makes it into the 11's range on AFR. The difference is unvelievable. Boost gets to 6 PSI, and holds, doesn't drop off at all. Everything seems to work like it was supposed to.

So, looking back, I can now guess that my plastic airbox must have leaked all along. The car has never run this strong since I built it. I will further guess the big spike in the original dyno curves are gone. I'll know when it goes back on the dyno.

So, all I need now is to tweak the WUR a bit, and get it a tad bit richer at low to mid range RPM.

Thanks! You guys rock!
