I'm Awesome
You can engage lean cruise in your stock ECM. If you install the EBL-flash by Dynamic EFI, it allows you to tune with your laptop and part of that is the ability to access lean cruise. I have it on my truck, and it works great. Got as much as 25mpg with my warmed up 350. Still tuning on my 383, we'll see how that goes.
