The Burger Motorsports JB4 is the best piggyback available. Power delivery and daily driving is buttery smooth. You will gain approx 50 HP and 50 torquezzzzz for about 15 mins of install time. This is also the best way to stay off the dealer's naughty list and still be tuned.
Selling because I am going a different route with the car. Thanks and happy buying!
