It's just varied maf cals, not a new map for each intake.
It's not a good idea unless you have a monitoring system. I tried several maf cals on my car, which has an AEM CAI. The Nano cals gave brutal torque but the trims were wildly all over the place. The AEM cal was really strong in the midrange but tapered off too much up high for me. The CP-e Excel CAI values work best and to beat all, the trims are closer to 0 than the AEM cals were. It gives back a touch in the mid for better high rpm power that is more progressive in delivery. Chris from HT said, as long as the boost levels don't climb too high over 5000 rpm, it'll be fine. Boost levels and taper seem the same as with the AEM cals, according to my logs so, Excel it stays.
