    For anybody still left alive out there, Project tC is still running the streets with the, pretty much stock, OEM engine, trans, clutch, axles with the TRD S/C blown to 15 PSI. Never could get the Greddy Ultimate E-manage to tune. Went back to just the TRD mapped ECM. Car run muchj smoother but was missing the power that it should have been producing. My DC Sports 4-1 header finally corroded away, so I stuck the OEM (cat still intact) back on. Man oh man, did that engine come alive! You see, the OEM/TRD mappings had been working against me cause the B1S1 Wideband sensor had been receiving skewed data w/o the primary TWC. So when the B1S2 Narrowband picked up the gas flow, it perceived it as something wrong, telling the ECM to adjust accordingly to compensate. Still, fact is, I have been running this S/C for over 60K miles, boosted to 15PSI for the past 30K, with no intercooler setup and the motor is still going strong as ever.
