Your trims are maxed out and you're running lean. Are you running the E85 back end flash?

Update your firmware and put all your user adjustment settings back to the default values.

As stated...you need to lower ethanol content to E30 or load the E85 BEF.

To update the firmware I can do that straight from the jb4 app correct and with the E85 BEF where do I find that?

Correct, and there is a sticky thread on everything you need to know about the BEF at the top of the N54 forum on this site. Or here: N54 MHD Back End Flash Maps - N54Tech.com - International Turbo Racing Discussion

I flashed the E85 map and updated the software but where would I go to reset all to default values?
