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?
