Nothing but good. gas milage went from 10 to 13.6. Mixed driving. I am running the 89 tune on 87 gas. Runs really well. I will be pulling my travel trailer next week, so will post on how well it pulls.

So you can't run a tune while towing? Or just not the 93?

Your doing great with 3.55 gear with 35's. Wonder how much better it would be with a set of 4.56 or 4.88 gears?
