The Ecotek is one of those gadgets that sounds too good to be true. it claims several benefits such as
Reduced Emissions
More Power
Better Fuel Economy
As usual I was very sceptical, but they guarantee their results and offer a money back no quibble guarantee and the feedback on the forums was good so I decided to try one. I went for the gold version with the extra filter at £49 for the valve itself including P&P. Fitting the filter was hard work and took some figuring out.
You then have to adjust it for your car which was pretty easy. The product instructions and documentation are very good as is the build quality. Initial opinions were to question how it could alter the mixture as I have a lambda sensor which would just richen the mixture again, but on driving the car after fitting it had a noticeable better pull below the power band and seemed to rev up quicker. It also has a distinctive whistle on over run.
So results are
Noticeable extra grunt and lower end
I estimate about 5%-10% better fuel economy
Strange whistle on over run (tell the kids its a dump valve!!!)
I am unable to test emissions but have no reason to doubt the claims, mine are 0 anyway
So conclusion is BUY ONE, it works
