James Fuller did what everyone with a 3.8 GM engine should do: He got The Groove!

While I haven't had any reports from him yet, he found it smoother and a lot more fun to drive, as those engines ADORE The Gadgetman Groove.

Now, you need to pay attention to those TB's boys and girls! You have to do a bit more to get to the back of the throttle plate, but seeing the faces of the owners coming back from their test drive is well worth the effort!
