DPF
As with any type of filter a Particulate Filter needs to be cleaned regularly to function properly. With DPF’s this is done by a process known as Regeneration which involves a combination of a Catalyst function in the system and burning the soot to gas at a very high temperature leaving behind an Ash residue within the DPF. Regeneration should be an automatic process taking place in the normal use of your vehicle, you may have noticed this in the form of a blast of white smoke form the exhaust on occasions.
DPFs have been in common use in passenger cars and light commercials from around 2003 in preparation for Euro 4 regs (2005), with Peugeot, Renault and BMW being early takers. Euro 5 (2009) made it compulsory for diesel cars and light commercials to have a DPF fitted and Euro 6 2014 will tighten this up further.
DPF Filter Delete/Removal ak remap DPF Removal software will ensure that your vehicle operates without the DPF being present. Most customers also benefit by having a performance remap alongside the DPF remap which provides even better gains than just the DPF Removal itself. The benefits of DPF removal are as follows:
- No expensive DPF replacement costs.
- No more limp modes when the vehicle decides to do a forced regeneration.
- Improved MPG due to the removal of an air restriction allowing the engine to breather better.
- Improved power output of the vehicle. We have tested many vehicle’s on our dynamometer before and after DPF removal and every single one has provided a performance gain. An example of one is the Fiat 500 1.3 Multijet 75bhp which gained 8bhp and 10lbft after having DPF removal.
- After DPF removal it is possible to use bio fuels as they can no longer cause issue to the DPF filter.
ECU Remap?
There are many benefits to a More BHP remap for your car's engine ECU (Electronic Control Unit).
Every More BHP ECU remap or chip upgrade will deliver: increased power and torque improved throttle response smoother power delivery, removing flat-spots where possible improved MPG during normal driving helping to reduce fuel bills and your carbon foot-printRemapping ADVANTAGES
- More performance and power when you need it
- Greater torque across the whole rev range
- Sharper quicker throttle response
- Smoother, quicker delivery of power
- Can be reverted to stock when needed
You have 3 choices to choose from:
Economy Map - Small Power Gain better MPG
Power Map - More Power & torque plus slightly better MPG
Max Power Map - Maximum power and torque, little to no MPG improvement maybe worse depending on how driven

Custom Dyno Tuning - Launch control, egr deletion*, decat files*, dpf off*, speed limiter removal and modifications (* Off road closed track events)EGR Solution
HOW DO EGR VALVES WORK?
The EGR Valve creates a loop back from the exhaust manifold to the intake manifold to recirculate burnt gases.The EGR valve has a solenoid which controls the valve which in turn is controlled by the ECU. The ECU operates the solenoid by using a duty request cycle in order to open the valve and recirculate the burnt gases. The Manifold Absolute Pressure sensor is then used to record the amount of additional gas which subsequently feeds back to the ECU as a control measure.
EGR VALVE PROBLEMS
As the EGR valve is constantly working with burnt exhaust gases they naturally have high soot content. This soot in the gases causes a build-up of carbon deposits around the valve operation area which in turn causes the valve to have a tendency to stick in various positions. For full engine performance the EGR valve is closed which creates a closed loop environment for the turbo system which allows it to pressurise. A problematic EGR can create an open loop environment for the turbo as it provides a feedback straight to the intake manifold and as a result can cause boost issues along with huge reductions in power and also fuel economy!BENEFITS OF EGR REMOVAL
- Restored Engine Power
- Restored MPG
- Cleaner emissions as faulty EGR’s create much higher soot deposits
- Can prevent DPF failure as the soot is caught in the DPF trap
- Can prevent EGR replacement which can cost hundreds of pounds
- Still 100% MOT compliant
software of most ECU types. Some companies will simply turn off the codes associated with it being unplugged but this is not the correct way. The EGR valve needs properly disabling to ensure it is not trying to recirculate exhausts gases whilst still physically working in the engine.
