I had the 2101 kit installed in mine. Which looks like the same kit minus the heads. I got the stage 2+ package installed by them and they cnc'ed my heads. End result is 399 at the wheels and fair driveability. I would recommend a stall tho. I'm still on stock stall and coming to stop car wants to push still so kind of jerky. But not terrible. I even upgraded to the Brembo brakes in front to help. Idle is as low as possible. To the point that stop and go traffic has stalled engine a couple times. Other than that 3000 miles so far and still runs like a champ.
