Yes, I have!

On a full fuel tank I can drive about 40-60 kilometers more than before, and this is because the engine does'nt need to work as hard as before the modification.

On the other hand, it is more fun to put the foot down hard, and that means a loss in fuel economy...

It all depends on how you drive, but you will get a better fuel economy with this modification if you drive "normal".


Try it! And if you're not satisfied, then put everything back as it was!
