Cayenne Sprint Boosters from GMP Performance

Shouldn't be a problem once you get used to it. We've had no feedback to indicate a problem in that type of situation. If anything it makes it easier to modulate the throttle accurately because there is no delay.

There is a 30-day money back guarantee, so if you are not satisfied for any reason you can send it back and we will refund your money. You just pay the return shipping.
But given the response we've had from Cayenne owners on these, there should be no need for that!
Feel free to PM if you have any questions about ordering.

You should have no issues with the warranty. The Sprint Booster does not modify any of the factory wiring, nor does it change anything else that could void it.
