i had a 3.90 gear change done there. they had a used dte unit there and the price on the 3.90's and install came out to $1000. $700 for the dte dif. plus my leaking unit and $300 for install. no issues with work quality or parts. car was in and out of the shop on the same day (saturday). i have 2000 miles on the rear end now and have had no problems at all. i changed out my exhaust shortly after the install and everything was tight and in place. the car was clean with no damage or surprises ( no damage or dirty finger prints anywhere and no hidden costs ) only one slight problem but it was fixed in a matter of minutes. the tuner didnt know the mn6/12 cars do not need to be reprogramed for a gear change. so he put the 3.90 in the tune and it made the speedo off. he put the 3.42 gear setting back in the tune and all was perfect. they were willing to stand behind their work. from my experiance with them i would have no problem letting them work on my car again.
