I for one have been at it for about 10 months (research and paranoia included Smile). HHO's been in the truck off & on for about 4 months now. Had a few nasty rounds with the outrageous vacuum of a Vortec V8 and trying to seal the jars. Oh, and I can't forget the whole spark plug non-fouler debacle (Good times....although they worked to an extent). The efie has been installed about a month now. So, a little over 500 miles a week, for 4 months and thats about 8k miles for yours truly.

What has been your MPG improvement once the EFIE was installed.

From 15mpg to 19mpg so far. Tuning is a killer!

It seemed liked when I installed the double stack plug foulers my mpg was all over the place. For my truck, I believe they just moved the sensors further back but not out of the exhaust stream. The exhaust stream is still the same but the sensors just see less of it. They still see it and I believe they diagnose the content of the exhaust gas, be it a little or a lot. From my personal experience, do NOT plug the foulers and block the O2's off completely from the gas flow. Did that and luckily I did my test just idling outside the open garage. It set off the detectors insideShocked the garage as the truck just ran leaner and leaner. I had to shut it off and unplug the foulers until I got my Dual EFIE from Mike. It was only on long trips with the cruise control set that the O2's could get a good consistant enough reading to snitch off to the PCM.

ps I just remember that I could only get any improvement by plugging the single large center hole that is the sole access to the exhaust stream and drilling 2 much smaller holes (very tricky) on either side to allow some but much less gas to get through.

The O2s must be reading the exhaust, Unless you go to an Open Loop tune and this can not be done without programming the computer to do this all the time, which I do not recommend, I would rather change the OL command parameters so that the O2s can begin controlling fueling sooner.
