Take one look at the power curve on the Boss 302 pull and you know this thing is working. Compared to the stock intake and stock throttle body, it boosted peak power by 31 to 468 rwhp. It gives up a bit down low, but from the midrange on up, it takes off like a rocket all the way to the rev limiter. UPR also added a Boss intake and L&M throttle body to its automatic '11 GT with an Airraid CAI and stock exhaust. It topped out at 447 rwhp.
