ok...typing something really fast and then shutting it down isn't my thing :o
a reset would already do alot...you got to weigh performance against mileage.
better performance does not equal better mileage.
getting in between the 2 will get you the best of both worlds and your engine will do ok.
running lean will give you a good (almost too good) throttle response, but will not give you the best performance.
best performance will not give you the best mileage...etc...
