TN and this was the truck that I sold performance mods with. I never took it to the drag strip or sled pulled with it. Most all these mods were done in the last 2 years. it's damn near bullet proof. I have it set for 650 rear wheel horsepower. which is conservative for this compound setup--and I never run the "MAX EFFORT" tune-just no reason to-it's so damn fast as it is! Reliable performance was the main goal. I haven't had any major trouble either. it's been solid. We closed down the diesel performance business and I'm trying to recapitalize. I have over $48. 00 in this truck. This is the way to buy a modified Duramax - My loss-your gain. If you have any questions. don't hesitate to give me a call. Blair Outlan 901-378-8877
