Chris Kristofferson from Iowa is a bonafide diesel truck fanatic. He drives a 2008 GMC 2500HD SLT X-Cab EFI. Kristofferson is concerned whether to maintain or remove the DPF Delete Kit which he had installed on his $47,000 truck.
He posted on a popular diesel truck forum, “I’ve been reading everyone’s posts about throwing the DPF in the trash using a PPE programmer and going turbo back exhaust. He said he misses the excitement of passing almost any vehicle on the highway. I believe messing with a ,000 truck can really cause some problem especially to those who do not know what they are doing?”
Kristofferson said he is planning to buy a six gund and PDA with an MBRF back exhaust but he doubts if it can give the same performance.
“The good thing about that though is I’ll be able to adjust on the fly,” he said.
Alex Santander of North Carolina, who drives a 2007 Chevy replied that ditching the DPF Delete Kit was the best move he had ever done.
“With a ,000 truck, you owe it to yourself to upgrade …. it took me around two months to keep things going,” Santander said.
One reader said he opted to check Banks + PDA. “I am thinking of using the dyno session and will update you with the result. I’m in colorado so the numbers will likely be lower than elsewhere — but the % gain should be relevant. If I were you, I’d just wait a couple of months.”
According to the post, he would most likely dump his DPF Delete Kit at the five-year mark when the warranty’s up.
According to him, he cannot distinguish the difference because both provide power.
He offered four reasons why he believes otherwise;
1) This often overlooked feature automatically reads EGTs and backs off power. Can the PPE/EFI live perform?)
2) Can be removed before going to the dealer, with no ECU residue
3) It is hoped to provide some MPGs.
4) No gauges to install, just look at the PDA.

Many new diesel trucks now include filter technology, more particularly, a device called diesel particulate filter otherwise known as DPF.the designers of the kit will guarantee the elimination of the soot of so called diesel particulate and drastically improve the color of the smoke coming out of the exhaust pipe. New environmental laws requires manufacturers to strictly comply with stringent standards on particulate emissions from diesel engines. Unfortunately, the process that ensues hampers power and fuel mileage in the vehicle, which is the problem that DPF delete kits address.
A process called regeneration burns accumulated soots that the DPF traps in the exhaust, resulting to an almost clear exhaust. The onboard computer found on the vehicle will have passive or active control. Among other things, the process introduces the concept ofback pressure, which is what happens when the spent gases in the exhaust are hampered by the tight bends in the piping or air vents for example. While others said the regeneration process has affected the fuel efficiency of their vehicle as power and fuel are greatly compromised. Eliminating the back pressure problem with DPF delete, thus freeing up the engine to work better, sends more power to the wheels, and allows it to burn less fuel. Several independent studies show an marked improvement to their fuel consumption between 4 and 7 mpg.
A standard DPF delete kit wouldusually include a DPF delete pipe, a touch screen programmer, aluminized or stainless exhaust and muffler, dual tailpiles catalytic converter delete pipe and standard tunes. The user may decide the component of the kit depending on the driver’s modification requirement as well as the improvement needed on the vehicle.
Manufacturers of DPF delete pipes, which function as direct bolt on replacement for the factory DPF, also claim that installation of the device can increase as much as 300 horsepower and500 lb/ft oftorque at the same time.The pipes can be used on Ford 6.4L Powerstroke , GM LMM 6.other diesel engines.7L Cummins Diesel engines, without having to use any check engine codes.
The law only allows DPF Delete Kits to be used in off-road diesel-engined vehicles because it interferes with emissions. Any on-highway vehicles caught using DPF Delete kits will be apprehended and the driver of the vehicle will be meted a fine.. Do not try to make alterations on the kits’ components or the warranty on the exhaust stack and EGR and turbo will be voided. Some users seem to believe that the level of improvement on engine performance is substantial enough and worth risking the engine warranty on their own work vehicles.

Thanks to the new Euro Emissions standards, the legislation which aims changes for vehicle emissions or 2009 and the years to come (specifically an 80% reduction in soot emissions), there will be an increase in the use of filter technology particulate filters in diesel vehicle exhausts – commonly called as diesel particulate filters or DPF. The wall flow type of DPF (also known as “traps”) catch 85-100% of the soot in the exhaust, and remove the appearance of visible smoke. But this might lessen the performance of your engine. A DPF delete kit can address this issue by removing the DPF, thus improving fuel efficiency and the performance of the engine power. But the law states that these DPF Delete kits can only be used on off-road vehicles and is illegal for use in on-highway diesel vehicles.
How does it work? The 6.4 DPF delete works just like any filter, such as the bag in your vacuum cleaner, for example, working to trap dirt and soot from the air of the exhaust into the filter. This filter must be cleaned out to maintain the performance of the engine. In a process called “regeneration,” the diesel particulates are burned at high temperature, leaving a residue of ash in the filter. However, despite the fact that DPF and catalytic converters can scrub away emissions, the process somehow invites a phenomenon called back-pressure, which is a result of the restriction of the flow of the gases out the exhaust as it leaves the combustion chamber. The gases enter the exhaust stack and then make an exit through the tail pipe. The restriction of flow is often thought to be caused by DPF, as well as by catalytic converters, mufflers, and bends in the pipe.
As the back-pressure increases, it adds more pressure to the engine to work harder to release the used gas. The harder the engine works, the more fuel it requires, and less power is also allocated to the movement of the wheels. These combined factors reduce the performance of the engine. The DPF delete kit removes the DPF, thereby reducing backpressure and thus building up engine performance and fuel efficiency.
Some independent tests run on engines after applying the DPF delete kits report a 26 to 47 percent increase in fuel mileage. While it’s true that emissions cleaners like DPF hampers the flow of the exhaust gas flow, it’s also true that free flow in big trucks is already built into the vehicle’s system. The kit also includes a flash device that reprogram the engine’s performance by boosting fuel efficiency using the truck’s on board computer. Thus, it would be safe to say that the DPF delete kit enhances overall performance by addressing these issues including the issue of back-pressure.
DPF Delete is primarily designed to increase engine power as well as fuel efficiency on off road diesel trucks.
