For those that are supercharged....

I can beat mine like it stole from me and it smiles back. It drives like a stock car. Kinda hard to explain as you'd have to drive a blown car, then drive a stock GT to feel the difference.. but where the stock car's power drops off, mine keeps going and going.. RPM being the limit. Run outta cam. Very streetable, very fun to drive. Powers there when you slam the loud pedal, otherwise it's as "docile" as a slightly modded GT when cruising

Drivability loss is and should be "0" if the car is set up and tuned properly. Mine drives like stock, idles like stock, and goes on 1000 mile trips just like it did when it was stock. Just keep the power in check, don't get greedy, and you'll be fine.

I drive mine back and forth to work everyday. Put about 15,000 miles on mine since I installed it and haven't had any problems. (Knock on wood) Driveability is just like stock.
