Are any of you guys using custom tunes, after market exhaust/intakes or anything else to help with MPG's on your Suburbans?...or just running stock? I'm curious if there are any solutions producing gains that are worth looking into. I mean I'm guessing there are no magic bullets or anything, but it seems like even a small gain would be helpful.
