TB SS MPG with Tuning Anyone have any experience with what improvements can be made to Trailblazer SS MPGs with some good tuning efforts? Thinking of getting one, but I feel like the LS platform can deliver much better MPGs than it is advertised to in that platform. Maybe Im wrong?... Thoughts/Experience?

I don't know about TBSS's but my dads 02 5.3 Suburban picked up about 3mpg highway from a dyno tune. We didn't even activate lean cruise. Picked up about 15hp too.

I would agree that Gen III's (such as the 02 mentioned above) can gain mileage through tuning. The Gen IV's & V's, not as much if it is not modified - GM did pretty good on the newer models as far as pulling the mpg out of them...

Electric fan, Electric water pump, 3.42 gears, full exhaust(lighter) and a retune, lighter wheels/tires, lowering, overall weight reduction. All of this will get you 18-20 city MPGs and your looking at close to 4k in parts. So it would take 4-6 years of gas to break even The truck just wasn't designed for fuel economy

^^^Yah I hear yah, I just bought one and its really fun, the family loves it and it feels safe. I am getting around 16 city/hwy to work and dropping kids at school. I am going against the grain with mine and trying to get this mobile brick above 23mpgs on the highway! Its only a 2WD so I am going to lower it and treat it like a giant station wagon that can roast the tires!
