The T7 system is programmed to give a "fixed" fuel amount depending on rpm's and airmass. The airmass is a value coming from the original (initial) calibration of the Airmassmeter. If you change a hardware part (airfilter, exhaust aso.) it will affect this calibration, therefore the measured value is not "correct" anymore ( 1 is not = 1 but perhaps 0.99 or 1.01 or whatever). So the lambdaintegrator will need to adjust the lambda 1 factor back (adding or subtracting depending on the hardware change affect) and therefore you have a fuel adaption.
Hardware changes have enormous impact on the MAF calibration.
Hope this helps.
