This is a little long, so sorry about that,

OK, still researching these darn diesel trucks, all the DPF deletes, EGR deletes, finding the parts is proving very difficult considering that selling them to the general public is illegal, and running them is also illegal (as you all know, so no secret there). So, I started researching legal ways to make all this emissions crap work and came across this from

"The main thing that is going to help with fuel economy is Better Fuel Atomization. What causes the poor fuel economy on these newer trucks is the fact that when the DPF becomes clogged the truck has to force a (Regen) cycle. When your 2007 and newer diesel goes into regen mode, the engine is literally using over a gallon of fuel in a matter of minutes. This is going to affect the overall average fuel economy.

So the bottom line here is we need to stop the filter from becoming clogged in order to stop the regen cycles.

Poor fuel atomization results in heavy soot content which clogs the DPF.

So how do we get better fuel atomization? Well it's easier than you may think, most Diesel Programmers increase fuel pressure, that is the easiest way to increase horse power so we start with a good tuner or programmer because increased rail pressure will result in better atomization. There are a lot of different tuners available on the market, but Edge Products makes an Evolution tuner that we have used a lot and the Evolution will work on all 2007 and newer Ford, Chevy and Dodge trucks with a DPF. H&S Performance makes the Mini Maxx tuner which is another excellent choice and they make one part number that fits all 2007 and newer Diesel Trucks.

Now that we have the required fuel pressure we have to make sure we can keep the injection pump adequately supplied with fuel to prevent cavitation, we always install a FASS Fuel System when we are modifying a DPF equipped truck. There are several reasons we use the FASS but fuel supply is the main reason.

Most people associate an aftermarket cold air intake with better performance and fuel economy, and it's true. An aftermarket cold air intake for your diesel truck is always going to help increase your trucks efficiency. It's not going to increase fuel economy 3 or 4 miles per gallon like some manufacturers would like you to believe, but there is a mile per gallon to be had there. So for $289 S&B Intakes makes a cold air intake for every diesel truck on the road. It will pay itself off in a couple of months.

Let's get one thing out of the way right now. DPF back exhaust systems are a joke! I can't tell you how many people have bought one online and then called me up to yell at me because it didn't change the sound of their truck and they didn't get better mileage..... REALLY! The DPF is what makes your truck quiet, the DPF is what is killing your fuel economy. Hooking up a bigger pipe to the back of the DPF is not going to change anything except the way the tail pipe looks. So if you want a better looking exhaust tip then buy one, but don't waste your money on a DPF back exhaust system thinking it is going to change anything else on your truck.

The single most important factor that is going to make your truck perform better is a Water Methanol Injection System. The methanol helps the diesel fuel to achieve a more complete burn so there is no heavy soot going through the exhaust. It also helps to cool the engine down and lower the exhaust gas temperatures. One of the best features though; is the fact that the water methanol is injected into the intake elbow or manifold which cleans any old EGR soot out of the engine. It also keeps the intake clean for the lifespan of the truck.

So with the lift pump, the tuner, the cold air intake and the water methanol installed your truck will be getting better mileage than a stock 5.9L Cummins that didn't have emissions systems. You aren't doing anything illegal and your truck should rarely go through a regen cycle if it does at all. A few local trucks we have done here in Washington state have reported that it has been over a year since their last regen with these parts installed."

Anyway, this is OLD technology, going back to before WW2, and lots of WW2 aircraft used this technology for better performance. I can see where this could actually work, just wondering if any of you have tried this yet, and what you all think. :ford:
