Stock LB7 Dyno Run

A friend of mine was heading to a dyno day today and asked if I would built a nice dyno tune for him to run in the stock class. He has a 2003 LB7 Duramax, the allison has had some work done due to it going out at 100k.... That was before I touched it. This engine has 160ish k on it and zero work done to it other than deleting the muffler.

Here is what it put to the ground. This is at 25psi. I would love to see what we could do with some turbo work. EGTs hit 1550 at peak torque and dropped to 1350 in about 3 seconds.
