Claims of increased power or increased economy are bogus on a modern computer controlled engine. Altering the mixture will result in the computer compensating or generating trouble codes. Increasing air flow will only result in more fuel usage. When it comes to aftermarket "enhancements," I use this rule of thumb: How likely is it that some small "mom and pop" outfit can "out think" or "out engineer" an engine or vehicle as compared to a $50 million development department in a multi-billion dollar manufacturer??
Just like the guy asking technical questions to an 8 dollar an hour parts clerk rather than asking a trained, experienced mechanic??
In my experience, I have learned that the engineers in designing an engine or a vehicle have to balance three main factors: 1) Performance to satisfy the customer.
2) Economy to satisfy the CAFE regulations.
3) Emission controls to satisfy the EPA.
So, logically speaking, is some kid in a garage in Anytown, USA smarter then the engineers? I think not.
