For a code reader, I use the TorquePro app on my phone with a bluetooth elm reader that plugs into the OBDII port.

My 454 'burb with 4.10s gets around 11.2mpg, back and forth to work. I did make 13.12mpg the other day running up the interstate to Iowa with a generator in the back at 72mph.
I'll check into the TorquePro app, thanks!

I did install a new Delco fuel pump while the bed was off, but I'll check the pressure just in case. Sure it wouldn't be the first time a new pump is bad.
