First I doubt that I am in limp mode. And as Wayne stated it is an 06 dbw car.

Second there is no CEL. And when scanning for codes nothing comes up.

I am using tactrix with ecuflash and romraider for tuning and logging.

The last codes that did come up were for fuel pressure and fuel temp. I removed both of those sensors when making my tank harness though. My tuner cleared those codes.

Could this be a simple problem like a failing front o2 sensor?
