I have a 04 2500 6.0L with the stock 3.73 gears and I have my tuner set for the 87 tune and I was acutally kinda dissapointed with it. I even ran it on the 93 octane tune with 93 octane gas and it was even a bit dissapointing. Pulls amazing up a hill but it did that before the tuner too. Only other mod is a volant intake. Exhaust coming soon. I want more power as well but am finding it hard to find.

2007 2500HD 6.0l, automatic with 4.10 gears here (Extended cab, reg bed). Just purchased 3 weeks ago. Only modification is the installation of the True Flow system. I'm averaging about 13 mpg in and around town. Ordered the Predator last week, so I hope to see what it will do.

How did it work out for you, Tailspin?

I have a 2005 2500HD gas, reg. cab long bed for a work truck. I usually haul around 500 - 1500 lb around in the bed all day in the city and get about 12 mpg.

Main interest is to increase my gas mileage! Has anyone in a similar situation found success with this, and how much of an improvement?
