About two years ago I had my car dyno tuned for an a/f ratio of 13:1 at WOT with my current mods. If I add a new plenum/TB, who thinks I would need another tune and WHY?
It's my understanding that if I have a programmed a/f of 13:1 at WOT, wouldn’t my computer strive to achieve 13:1 after the bolt-on plenum/TB? Wouldn’t my oxygen sensors read the additional airflow from the larger plenum/TB and add more fuel to compensate until the a/f reached 13:1 again?
The result should be more horsepower and torque. However, the if for whatever reason the computer does not account for the additional airflow into the engine, my a/f ratio will run leaner than what it currently is right now. That concerns me.
