Is this a good way to get a lean cruise? Other than the fact of to lean and melting things but it's a DD and I'm looking to get a little mileage out of it but want to keep it reliable. Stock 6.0 in an 02 Denali.
Another thought I had was changing the stoich setting from 14.7 to 15.5 or whatever would the O2's work accurately at that lean of value?
