I Want My Mpg

The ECU automatically adjusts air fuel ratios, thus the purpose of the intake is to increase horsepower by improving airflow. Increased horsepower comes from more fuel burning. More fuel burning = lower MPG.

I still dont understand why you guys attempted to tell me or correct me somehow. Im baffled at the response you guys gave.
More fuel burning EFFICIENTLY will cause an increase of MPG(by 1-3).
That's why people with F/I have low mpg. They need to constantly adjust the A/F ratio depending on the weather.
 
I was responding on you saying to another guys post that intake increases mpg and then you contradict yourself somehow and try making a point which was an epic fail, I'm baffled and hope you dont give advice too often.
When was I contradicting myself?
All I said was an intake will not force but have a better airflow thus the engine will breath better. More fuel will be dumped into the engine but to correct running rich, the ECU will autoadjust the a/f ratio. Thus, the added fuel dumped into the engine will burn more efficiently. Engine Breathing better = good. Engine being forced to breath better = bad for mpg.
Get it now?
