Need a calibrated Mass air for S/C?

You want a maf with a n/a calibration.

They dont even make them with the S/C tune anymore. I talked with Professional Mass Air Systems about it when I purchased mine. They said the S/C calibration causes surging problems when going from a cruise to downshifting and flooring it. I guess it runs too rich at part throttle. So now they just sell the one calibration and the tuner will tune around the rest of it. Cuz I freaked out when I ordered the S/C calibration and got an N/A one in the mail.
