Update - After about 3/4 of a tank on 93 that was already in it before I installed the canister I got 15.4 mpg. We had some cold weather and I let it sit and warm up a few days so this isn't a very good test yet. Filled up with 93 today and will report back next week.

Another small update. I drive a few miles on the highway during the week and today I looked at my instant mpg. Normally it will read 18-23 mpg, but today it was up to 20-26 mpg. Sometimes when I draft behind someone I can get it to increase, but I was the only one around at the time. Could be a tail wind, but I doubt it would make that much difference. Not drawing and conclusions, but it would be really nice if this continues.
As for driving habits, i'm the type of person who drives 50 mph in a 55 because my instant mpg is higher so I don't think I can change them too much to skew it. Just have to wait and see because this seems to be too good to be true.

Some of you may have seen it on Horsepower tv, but they ran a dyno test on a ls1. It showed the motor used less fuel/hr using this product. They did several pulls using higher octane and 89 with generally the same results. However, it was only a few pulls and was a paying sponsor.
I hope you have good, long term results. How close is that line to the exhaust pipe?

Tank #2 - 16.8 mpg. That's 1.1 mpg gain over my average. I haven't seen the big anomaly that I had one day on the highway, but the instant mpg seems to be up about 1-2 mpg and seems to stay more constant rather than jumping around. I'll post back up after my next tank.

No way, the computer would try and compensate for the lean condition, by adding fuel. Also if he is externally regulated, the fuel pressure would be unaffected, but the flow may drop. Plus I think you would notice a drop in power and kr at WOT....
