I will assume, for one moment that all Pulstar claims are true...
It cannot be easy to bring a "legit" product to market with the promise of fuel savings. There are just too many scams out there. I think it is great that you have chosen to post here, and I do not envy you the challenges you as a company face due to all of the scams.
I have thought about your plugs, but the ROI is just a little long for me (assuming a 6% gain). That and it seems that most things do not work on three cylinder engines to the extent they do on larger 4,6, and 8 cylinder motors.
Again, thank you for posting here.
