    Wooohoooo!! I finally was able to buy my first 6.5 TD in a Suburban. I've worked on the 6.2's in the past and the 6.5's a few times and have always liked them. Now...for the real questions.

    1. What is the HP/TORQUE of the 6.5 TD and 6.5 TD Hight Output?

    2. I believe I have the 6.5 TD HO (vin code F) but how do I make certain?

    3. It has 4.10 gearing and I got between 15-16 MPG on the trip home at 65MPH which is about what I expected. How much of a MPG drop should I expect when I tow my 4500lb camper?

    4. Is the stock turbo wastegated or not? I'm assuming not.

    Thanks for any info you can give. I'll be on the 6.2, 6.5 page soon, but hey....I've been hanging out here long enough to know there's some killer brain power here too....why not tap it! Thanks
