Really sharp Roush charged 3V that was in for some custom tuning, customer did a great job on the car! 75% of the cars that come in for just tuning have all kinds of issues, this car was pretty well done! I suspect the car doesn't like the existing plugs and the stock exhaust is definitely holding her back some, probably some more power to be had with a few changes/upgrades...
