2006 Honda S2000 Greddy turbo kit carb flash tune P0172

[s2krene]

I have 2006 Honda S2000 with a Greddy turbo kit and running the carb tune. The only mods installed is a greddy RS race catback exhaust and suspension. I have fixed a few leaks and replaced both oxygen sensors with no change. The P0172 keeps getting triggered at around cruising speed bout 78 mph and the scanner Long term trim is around -22 to -24. The engine doesn't seem to lag and runs great. Any help would be appreciated.

Are all parts CARB approved?

The car has all the original parts that come in the Greddy CARB legal turbo kit, stock engine and catalytic converter. I'm also running the carb legal tune included with the kit. So yes from what I know of everything is CARB legal.
