ALS is something you probably don't want to mess with, by nature it has a habit of destroying turbochargers. I'm don't even think you can buy an ALS commercially.

A turbocharged car will always be faster than the same car without a turbocharger. However, a turbo Sprint will not accelerate faster than a Corvette...ALS or not. Who's faster has a lot to do with what type of cars are being raced.

Remember, lag happens before the turbocharger creates boost, so acceleration during this time will be the same as the NA car's. Your turbo lag is the NA cars full throttle acceleration, only their car never gets boost.
Lag only seems like you're going slower because you haven't got boost yet, in reality you are accelerating at the exact same speed as before you turbocharged your car.
