Chip contest

[DRW]

WOOHOO!!! I WON!

Sorry about the drop in mileage, my guess was based on lousy wintertime weather. Are you sure the weather didn't have an effect?

I promise I'll use the money for a good cause, probably get a little more coroplast or some screening to complete my underbody cover. Maybe try a rear wing or wheel fairings.

or beer! hahaha

I bet a good way to get better FE on these big PSD's would be to have another gear. Like a 2 speed dif. The first for towing and the second for running unloaded. The higher gear would keep the RPM's down and simply use the tourqe. The truck would feel a bit sluggish off the line, but one rolling you wouldn't notice.

Honestly, these things have more power than is needed. I know that there are kits that provide an extra overdrive. About $4000k for it. Even if it helps FE a little you wouldn't save a $.

No, just some people aren't pulling enough. And one can't complain about the resale. Back to $$.

Why doesn't Ford offer a 3.23 or 3.42 diff? The Powertroke has more power than God, it doesn't need 3.73's, or even a 2 speed axle.

Top gear on the E4OD and the R4100's were a .71 ratio. 3.55's are tall if you're gonna pull a 24ft enclosed trailer, or larger, loaded up for any regularity. 3.73's are a nice compromise.

I don't know exactly what the new transmissions have for their top ratio, but I'm betting its very similar to the previous, but it has more gears now than four.

I've got a Sniper Diesel Tuner kit on the way. I think you can program a lean burn for when you are running unloaded. You can also load a tune into a chip. So this way you can have one in the ECU and one on a chip. Econo / Towing

I'll post back after a few trials.
