I'm no expert but to me that sounds like there is a mixture problem. I've heard that in some cases the ECU uses a "Get You Home" mode that ignores all the sensors and just chucks fuel down the throat of the engine... could that be it?

The hot-wire EFi does have "redundancy" in the sensors, depending how many are fitted.  My LSE will run without an AFM and Blue has no Lambdas, road speed sensor or Air valve but it's quite economical, for a V8.

Barrie, if you are down on power then the lack of economy goes with it. Whether it's down to the exhaust I can't say, it's possibly you have overdone it though.

I know some engine tuners will test a big bore exhaust by fitting a restricter to the tail end (a narrower pipe) that will overcome the effects of an excessive bore, somehting for you to try.
