Driving with no intake
Engine space and a nice growl at 2500-3500 RPMs. My dad was in my truck today and said "You always complain about gas, but you are shooting off every time you come to a stop." Next light I really let it go, and he said "Wow that thing sounds meaner just going along than when you floor it"
Just keep an eye on the A/F ratio. If you set a CEL, you know you are too far out of line. The 04-08 M were on the edge of lead when shipped from the factory.
