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.

I agree. Using an in-tank fuel pump and a nice multi-port injection system would likely be a world of difference.
