The idle can sound how you want, it will chop a little at park, but if you bring it in and it will really start to shake the car. I had my exhaust cam actuator fail and it put the exhaust cam in full retard mode, which caused loping and loud backfires. But I don't like it since I need the engine to make as much torque as possible in idle to turn my supercharger when it is installed.

Depending on how many RPM's you want to spin the engine, you can trap in 3rd with bolt-ons with 3.91 gears. With my converter locked, I hit 102 MPH @ 7400 RPM. My wife's Mustang V6 shifts into 4th at the 1000' mark and still runs 0.5 seconds faster than my Camaro, so the shifting isn't a problem if you get the shift times low.

For the gains, I haven't been to a dyno yet with it, and the one time I went to the track with them I had no clue how to tune the low-end part so my 60' was horrible. My MAF before would read a high of 31 lb/min, I'm over 35 lb/min now, and that is a huge gain.
