Eh yeah kind of. It increases the torque to the wheels, but not the top end power. Mine is definitely faster on an autocross course digging out of corners with the 3.38, but I'm shifting all the time. I'm dialing it back to a 3.23 this year so I still have 5% more torque over the 3.07 but it's not so aggressive. The torque bump is awesome!
