This isn't intended to be funny...

Don't push down on the accellerator pedal as much.

These electronic diesels are significantly more efficient than the original non-electronic 3116 of which they're based upon. In the 3126, the 190 horse motor had different componentry than the 325 horse motor. You needed to replace the pistons, turbo, balancer, fan, injectors & some other bits to go to 330. Now I believe it's just turbos & injectors to jump the entire range and just reflashes from 250HP up.

Bottom line- you want the power, you have to feed the beast.

Sort of in relation to this...

The automakers are now considering putting gas-guzzling gauges in automobiles to illustrate in real-time when a driver is consuming excessive fuel. They theorize this will result in a 10% drop in fuel usage. What an epiphany! BMW has been putting theser gauges in their cars for more than a decade- nothing more than a manifold vacuum gauge.

I have a tree position chip in my f650 with the c7 motor, it woke the truck up a great deal, but milage ahhh about the same!!

joke?NOPE ! JUST THE FACTS. NOT A BUNCH OF ENGINERING MUMBO JUMBO. HE ASKED A SIMPLE QUESTION . SDR JOHN, CHECK WITH YOUR CLOSSEST FORD OR CAT DEALER TO CHECK YOUR PERAMETERS IN YOUR ENGINE BEFORE YOU DUMP A LOT OF MONEY IN IT. I BELIEVE IT IS ALL READY IN YOUR C-7 ACCERT 300 CAT TO DO WHAT YOU WOULD LIKE IT TO DO,. IF NOT AT LEAST YOU TRIDE THAT FIRST. I DID AND HAPPY EVER SINCE. GOOD LUCK.

Thanks guys for all the input. :D
