If you are driving in the city, that's probably the best program to use there. It's a program that helps you get a lot of weight moving from a standstill. And, in pure city driving, I think 13.5 is pretty damned good, considering that you are at low speed or stopped much of the time.

If you asked for a performance tune for city driving, it might very well use more gas. That sounds to me like you wanted something to burn rubber off a stop to get to the next stoplight faster than the other guy.

And, if you asked for a tune for the highway, it's not going to be right for the city.

It's very hard though, to get into your head here. I'm honestly not sure I understand what it is you're looking for.

I was VERY specific when I asked for my tune. I wanted something that would help me pass someone on a two lane road in the 60 mph range. It does that perfectly.

In city driving (New York?) your mileage is going to suck big time no matter what you do. I get about 13.X MPG in Tucson, where the lights are a mile apart and the speed limit (that no one obeys) is 45.

AHHHH!! finally some clarity. Yes I am driving around the city in perf 87. And yes I am saying I am getting better mileage in tow, than 87 performance.
See when I ORDERED all I did was tell bill what I did to the truck. But since I wasn't "towing" didn't think I needed to worry. ya know since we all want some performance from the big 8. I was more concerned about mileage .Guess I probally should have just kept asking.
Now don't get me wrong, the 87 perf has woken up the motor just fine,But I wonder if I am gettign better mpg's on 87 tow should I just put it there? and was the 87 perf a miss use of my money. Not a waste.. cause its fun to have.
