Stage 1 TP tune improved my fuel economy noticeably. In the 750 miles since reflash I've averaged 26.5 MPG (computer says 27), versus about 24 before hand.
Last week on a trip to and from Vail, I managed over 28MPG with a cruising speed of 70MPH. Not sure what the trip computer said for that short trip, didn't pay attention, but it's typically a bit higher than reality.
I thought TP maps were more aggressive than Cobb maps. (I'm not sure about that actually. Can anyone confirm?) Don't get me wrong, I want to have fun in my car. But at the same time, I don't want to run a tune that is so aggressive it causes my car not to last as long as it could.
Yes in general the TP maps are more aggressive than the Cobb maps. However, I seriously doubt 99.99% of people would be able to tell the difference in their butt dyno if they drove one versus the other back to back. Overall the Cobb maps are less aggressive and safer because they're tuning for a customer base probably 1,000 times bigger than TP if not 10,000 times the size!

As Scott said though, you still probably wouldn't be able to tell a major difference between the two. Now a dyno tune, that's a different story. You'll notice that.
