What is engine litre size? Use a fuel pressure gage and check fuel pressure. Not only check for proper fuel pressure, see if pressure will hold for bit, with everything off. If pressure drops like a rock, you have a leak. Any applicable trouble codes? The cts could cause the fuel trim to run rich?
I haven't heard of programminmg to bypass the 02 sensors? There are a lot of things I haven't heard, lol. If your only running in open loop, that will hurt your gas mileage.
