I only know of one person here who tryed a extrude hone.
He was doing a super CRD build which also included a custom built turbo and custom GDE tune.
You achieve the same effect by programming the ecm to run at higher fuel pressure and open the injectors longer.
In any case, your not likely to gain any mpg.
If you want to know what a 25 HP increase feels like:
1. Get a MPPS 13.02 cable and software.
2. Use it to read your ecm tune.
3. Save your current ecm tune so you can reload it later.
4. Load a free Yeti 811 stage 4 tune (assuming yours is an 05).
5. Feel you torque converter shudder
5. Unless you have a SunCoast TC!
As to the honing, they are basicly micro polishing the openings of the injectors which may slightly enlarge the openings up just a miniscule bit. Therefore they will pass a little bit more fuel flow when open and thus make a little more HP & torque. Downside, this will tend to lower rail pressure due to increased flow, so ECM will call for more pressure from CP3 which will have to work a little harder and you may get a little bit more black smoke due to the slight change in air to fuel ratio.
Personally, I would not recommend it on a daily driver, but very good for high performance diesels or if you are planning on doing some heavy duty hauling and are not real concerned about fuel mileage!!!
If you want more power and torque like Flash stated, get a MPPS cable and install a Yeti stage IV hot tune! But you better have a GOOD torque converter that will handle it or you will get lots of shudder...
