i was unhappy with my 2012 kit. i put on 500 miles. in those miles i blew 3 tps sensors, had oil leaking out of the turbo oil cap and exhaust covering EVERYTHING in oil, including my clutches/ the o rings on the intake box rubbed threw causing a boost leak. when the sled decided to run it ran great, except for blowing belts like crazy from the oil. the main reason i took off the kit was because me and 3 dealers could not figure out why i kept blowing tps sensors. i pulled the kit off and haven't blown a sensor in 400 miles. maybe i had a lemon kit, but i really hope justin fixed all the 2012 problems caused they ruined my season.
