What’s the greatest tuner for fuel efficiency on a 2002 6.0 Escalade? I love the car, but it consumes too much gas (14mpg average). I am prepared to work on it and have considered installing a turbo (low psi) for fuel efficiency, but I don’t want to blow up the engine. I am just looking for your advice on the optimum fuel efficiency tuning.

Oh, you are attempting to make that gas guzzler into a sly fox, right? Good luck increasing those MPG numbers!

Rebuild it as an AFM/DFM disaster, with highway gears in the differential and an 8 or 10-speed transmission.
Seriously, that’s what The General has done over the last 15 years or so to increase mileage.
