Beach, I've had one of these
FuelCat in my Harley for about 2 years.
Some will say it's snake oil, others, like Steventhechef will say "good to go". There are plenty of people selling junk that is supposed to do something like save fuel, increase power etc, but the fuelcat seems to have research behind it.
It did reduce the pinging on the old girl considerably and as she is ridden only once a fortnight or so, she still fires up on one kick. Consumption? Never had an accurate odometer so never did any tests, except "seat of the pants". Haven't put one in the S3 yet, but may do, just haven't ever worried about it.
