The auto industry can be a weird business, right? Imagine spending upwards of $50,000 on a tuning kit that makes your car go one second a lap faster on a race track. It seems weird to even think about, but it happens all the time in this industry so nobody bats an eye anytime a tuning firm charges whatever it does so long as the results are justified. Chevrolet, though, has a business that doesn’t revolve around these power and performance upgrades, and that partly explains why the automaker is charging a pittance for a software upgrade that ends in the current-generation Corvette getting a decent performance spike. So much so, in fact, that it improves its lap time around the automaker’s 2.9-mile Milford Roads Course race track. The cost of this software update? $350.
