GTM Performance Engineering: Mild 7 A/T Twin Turbo Build

Don't worry about it. Sam's got you covered.

The difference in performance will blow your mind.

Basically the factory VDC is a nasty, intrusive POS that gets in the way of having fun and if you turn it off, then you could end up wrapping your car around a tree if you're not careful. The factory VDC closes the throttles and murders the power for a bit before giving it back to you. On corner exit, this stability control strategy is a total killjoy and really takes the fun out of the car.

The Racelogic, on the other hand, is barely perceptible when it is doing its thing. Basically, it interrupts the firing of a single fuel injector for a single cylinder so that it takes a gulp of fresh air instead of a fuel/air mixture to limit the power. It does this on a rotating schedule as needed so that each cylinder gets a fresh air charge in turn. As you can imagine, this happens extremely quickly. The traction control monitors the wheel speed every thousandth of a second and at the first hint of traction loss cuts just enough power to maintain traction so quickly that the factory ecu doesn't even realize you were about to lose the tail of the car. In fact, you probably won't notice either. All you'll feel is hard acceleration that maximizes the grip your tires and suspension can hold.
