When you experience a significant tick up or down in humidity, air temp and possibly also barometer, carbs will show a significant change in engine performance because they have a more difficult time correcting the fuel delivery in these situations. A MAF (mass air flow) based EFI system will do a much better job of correcting fuel delivery. The sluggishness you feel is caused by a decrease in air density and an increase in humidity both of which displace oxygen in the air making the engine run rich.

A MAF-based EFI system will measure the actual air mass injested by the engine and correct the fuel delivery to exactly match what the engine needs. You will immediately feel the difference in throttle response and the vehicle acceleration your seat of the pants dyno reports. Your Cobra will be able to accommodate these climatic changes as easily as your daily driver does.
