I was curious if the pros around here could take a look and possibly see any blaring problems in with this tune.Its an 5.3 running on 01 5.3 os with the tables copied from an 05 5.3. I have done this before and its worked fine but for some reason I can't get this engine to run properly. It ran great one time with the current tune. I shut it down then restarted a few minutes later and it does not want to run right. Also the timing is jumping everywhere at idle, and for some reason its not populating my fuel trim tables, just getting 0's. Any ideas?
Hope someone can help. Thanks
