My mission is to get my suburban to 20mpg combined city / highway. So far I'm getting about 13 with a tune-up due anyway and all stock parts.
I think it's possible with better air intake, exhaust, filters and ignition.
Does anyone have experience with a msd ignition control box like the 6a? Also, to maximize the effect, what distributor, spark plugs and wires are the best with that? What fuel filter is the best?
By the way, I put in a K&N air filter and turned the air cleaner lid upside down. That easy trick helps quite a bit with acceleration, and it also makes the truck sound much cooler. I haven't measured yet, but it seems to help gas mileage too. I also just ordered a throttle body spacer that lifts the throttle body up 1 inch. I'll post my experience with that once I put it in...
