More fuel means more power. The importance of optimizing airflow before changing the fuel curve cannot be overemphasized. We test every engine to be sure it is a candidate for more power. I will never cease to be surprised at the unrealized power potential that is trapped by intake and exhaust restrictions. When these are corrected, engines show their true colors.
More fuel means more power.
But without the proper amount of air to mix with the fuel, you have a disaster in the making. On the contrary, with proper engine airflow, engines utilize fuel efficiently to produce more power safely. We've had a great many readers say they would be very interested in doing a Banks power upgrade, but they're fearful that by doing so they will put their 100,000 mile warranty in jeopardy. And I would know if there were even one instance. But I hasten to add, any dealer who denies a vehicle warranty due to the installation of a Banks product is making an illegal statement, in violation of the Magnuson-Moss Warranty Protection Act.
