2001 lb7 duramax. i have had this truck a few years now and it has been great. the engine was rebuilt at 200k miles and the trans at 190k before the motor. truck at rebuild had a compound turbo set up and was making way more boost but now has a single 67mm to be more streetable. it is tuned using a 5 tune auto cal and i have an edge tuner just for gauges. this truck is tuned way down. it has 75 over injectors so with compounds this truck was making around 800. I haven't had the truck dyno'd on current tune since I've been dailyng it but its still pretty quick for an old diesel but it can for sure be tuned up. only issue ive ever had was the rear adapter housing on the trans cracked. i replaced it with an upgraded aluminum housing and installed a ppe transfer case brace. sometimes when I start the the truck there is a check engine light p0380. its a hard start code, the truck has no intake heater and bigger injectors so starts harder in the cold and sometimes gives a code. I just delete it with the edge. its a Great truck but I bought a new one and no longer need it so I am selling it. I have attached all the work orders I have available where you can see whats been done.
