^ Not true.

Tuning a stock engine with an intake, header, and exhaust can yeild quite decent results over a stock ECU.

I'm sure the stock ECU compensates for changes within the intake runner, air temperature, map sensor, fuel, primary & secondary 02's, etc. so i can't imagine too much of a gain...may be able to smooth out the curve though
