So, like many, many before me i was wondering if anyone would care to take a look at a log and tune and tell give me some advice on where to start or if things look messed up. this is a 5.3 out of a 2000 yukon 4l60e and put in a 81 cherokee chief. It seemed to run fine in the yukon but in the chief it's a bit lack luster. This is my first time looking at the tuning side of things and i have started to read but boy is it a lot to take in. So while i'm tryin to school myself have a look and tell me what you think.
Thanks
Jeff
