I was wondering if my 2004 suburban 5.3L has individual coils or just the one? I was wanting to increase the performance/mileage with some aftermarket ignition stuff. Just wondering. thanks!

How big on the tires did you go? Did you correct the speedo, and if you went noticeably larger on the tires a gear swap will help get some back. Obviously the increased weight and rolling resistance will hurt one way or the other. I maybe only lost .5mpg after a 6 inch lift and 35"s. Going 3.73 to 4.10 helped since I do mostly highway driving, where the 4.56 would give more grunt but would have probably hurt a little on my daily route since it would have increased the RPM's by a few hundred.David

Look for top tier fuels. Those are your best choices. I run Shell whenever possible and have had the best results with it. I seldom put additives in my tank.
