My before #'s were almost identical as yours before roll back. After rollback no change, maybe even less.

yeah, I ran the gryphon for a solid year thinking. Where in the heck is all of the great mileage that everyone is talking about? Then I read into the FICM roll back and noticed that I had a VXCF7xx. The cash hurt to pay for it up front but the run I just put on that ole beast made me grin every time I put the hose in the tank. It isn't much but now my big ole cow gets just as good as my wife's Nitro.... she

![]() If you haven't already, check out the EBP sensor and see if it, or the exhaust tube to it, are clogged. Clearing out the sensor and tube just might help. ![]() Let me know what you find. Tim, Those are awesome numbers! I'd say they are probably above average, but certainly not going to complain. ![]()

Where do I find the EBP? Would it show up on a code reader? Yep. Stuck at 15.4 mpg with the programer. My '04's would run in the 18's on the same roads with the programer.

Oddly, the EBP never seems to set a DTC, even when clogged. The sensor is located on the Drivers side of the engine and connects to a tube which runs to the front of the driver's side exhaust manifold. It's pretty easy to find. Let me know if you have any difficulty locating it and I'll see if I can get a diagram of it for you.

usually located on top(bolted to) of the thermostat housing, hope this helps....i to will looking at my sensor, haven`t seen the improvements i was hoping for in the mpg after doing ficm reprogram and ecm/tcm rollback and new custom tunes. the tube is clear, may just replace sensor and try that(not expensive part)....other then that, truck works awsome....thanks Bill

Checked for the EPB valve this weekend. Could not locate one. Did they do away with them when they upgraded the heads in the '05-'06's??????

Nope... still there. Front of Driver's side exhaust manifold has a stainless steel tube which leads to the sensor.
