just looking for some options (MPG's)

[907DAVE]

Just pick up a decent 4'' exhaust and a real cold air intake, couple those with some good programming from PHP and your fuel mileage should increase substantially.

I like the idea of an exhaust brake, just not what it is really doing. High exhaust back pressure on stock 7.3 valve springs (weak) is probably not the best idea.

I personally have never used one on a 7.3 so I do not know if this would really be an issue.

Personally I would rather replace brake pads then pushrods and transmissions.
