Does a CP3 conversion require tuning?

Description. LDS CP3 Conversion Kit with Recalibrated Pump, No Tuning Required. LDS CP3 Conversion Kit with Recalibrated Pump, No Tuning Required. This is the CP3 Conversion Kit to use when your truck has had its DEF removed, is already tuned and retuning is not an option. Our Recalibrated CP3 Pump eliminates the need to retune.

How hard is it to do a CP3 conversion?

The CP4. 2 to CP3 conversion is relatively straightforward (as much as it can be when accessing an injection pump sitting at the very front of a 6.6L Duramax LML engine’s valley).

Can you swap a CP4 to CP3?

The Industrial Injection CP4 To CP3 Conversion Kit is a sure way to increase reliability and performance of the fuel system in your 2011-2016 GM 6.6L Duramax LML. Unlike other CP3 conversion kits on the market, the Industrial Injection has no start-ability issues.

Does a CP3 add horsepower?

Double Your Potential. On its own, the CP3 produces 24,000 to 26,000 psi of fuel pressure and can support a truck making approximately 550 horsepower at the wheels. When combined with a second (stock displacement) pump, the potential to make more than 1,000 horsepower is on the table.

How hard is it to do a CP3 conversion?

The CP4. 2 to CP3 conversion is relatively straightforward (as much as it can be when accessing an injection pump sitting at the very front of a 6.6L Duramax LML engine’s valley).

What injection pump is in the L5P?

Denso HP4 injection pump

Are all CP3 pumps the same?

All factory CP3s share the same displacement. However, due to slightly higher efficiency right out of the box, the Duramax pump will flow 195 to 200 lph on a flow bench, while a Cummins pump will put out 180 to 185 lph.

How can you tell the difference between CP3 and CP4 pumps?

Basically whe a cp3 quits working it just quits without exploding. It’s typically a slow decline. The cp4 on the other hand doesn’t have a pinned piston and if it rotates slightly it tends to explode and send tiny bits of metal all through your fuel system.

How much HP can a CP4 handle?

Roadblock #2: The CP4.

The Bosch piezo injectors used in all 6.7L Power Stroke engines are quick-firing and capable of supporting big horsepower (700+ rwhp).

Is there a recall on CP4 pump?

Stellantis (FCA US, LLC) is recalling approximately 222,410 units of its 2019 to 2020 Ram 2500/3500 pickups and Ram 3500/4500/5500 Chassis Cabs equipped with the 6.7-liter Cummins turbo diesel. The recall-affected trucks are equipped with the Bosch CP4 high-pressure fuel pump (HPFP) that could fail prematurely.

How much HP can a stock CP3 handle?

A healthy CP3 will handle 30% overs fine. 45% overs will drain it on a long run if its older. Lift pump is a must for anything over stock that’s tuned over +150hp.

How much power can a CP3 handle?

In both Cummins and Duramax applications, the factory Bosch CP3 pumps can only flow enough fuel to support about 600 hp at the wheels. Adding more fuel via larger injectors or a bigger pulse width tune at more than 600 hp will result in a drop in rail pressure, which leads to less horsepower.

How hard is it to do a CP3 conversion?

The CP4. 2 to CP3 conversion is relatively straightforward (as much as it can be when accessing an injection pump sitting at the very front of a 6.6L Duramax LML engine’s valley).

How much HP can a L5P handle?

The Stock Injection Pump Can Support 770rwhp!

Is the L5P a good motor?

The L5P is considered the most reliable post-emissions Duramax made to date. With the removal of the CP4. 2 fuel injection pump and various improvements made to the block, pistons, and other internals, the engine itself is extremely capable and reliable.

What size turbo is on a L5P?

L5P 17-22 RDS 64MM Duramax Turbocharger Tow

The RDS L5P 64MM is a great upgrade on the 2017-2022 trucks. Below are some of the features of this unit: 64mm 6 blade billet compressor wheel; 10 blade “stock size” turbine 100% factory…

How do I know if my CP3 pump is bad?

There may be a surge at idle due to low or no fuel supply pump pressure to the high-pressure pump. Knocking can be heard if the actual versus desired are too far apart which may be a bad FCA or Fuel Control Actuator.

How do I know if my CP3 Duramax is bad?

The rough/lope idle is caused by excessively high rail pressure at idle, if the CP3 is worn out there is NO way it would cause HIGH rail pressure, it will only come up short of commanded. A good way to check is get a scanner that reads actual fuel rail pressure. At idle it should be around 5k psi.

How does a CP3 pump work?

In order to meter the fuel into the chambers, the CP3 has an internal metering/lift pump built right into it. This pump takes the fuel at supply pressure and boosts it to pressures between 80 and 180 PSI depending on what is required.

How much fuel pressure does a CP3 need?

If you are running a CP3 in a high-performance application, we highly recommend installing a fuel supply pressure gauge to ensure there is correct fuel pressure at all times. Recommended feed pressures for CP3 and CP4 equipped engines: Dodge/Cummins ’03 – ’16 (5.9L & 6.7L) no less than 8 PSI / no more than 15 PSI.

Is a CP3 pump a lift pump?

The lift pump is the pump that supplies the cp3 injection pump with fuel. The cp3 is the high pressure pump that supplies the fuel rail with fuel.

How much does it cost to replace a CP4 with CP3?

This includes all hardware necessary to replace the troublesome CP4 with a bulletproof CP3, requires no tuning changes, and still maintains factory emissions control equipment for $2,600 MAP. S&S also offers two other versions of LML CP3 conversion kits for competition applications which don’t require after-treatment.

How much does an LML CP3 conversion kit cost?

S&S also offers two other versions of LML CP3 conversion kits for competition applications which don’t require after-treatment. One tuning required version for $1,780.00 MAP, and one drop-in no tuning required for $2,175.00 MAP.

Do I need a new fuel pressure regulator for CP3 conversion?

It is highly recommended to install a new fuel pressure regulator in the driver side fuel rail with every CP3 Conversion install. GM Part # 12611872 WARNING This product is not legal in the state of California.

How do you put a CP3 on a CP4?

Bolt the CP3 to the block adapter using the 3 flange head bolts provided. Torque to 20 lb./ft. 2. Install the gear and nut from your CP4 onto the CP3. Torque nut to 75 lb./ft. –DO NOT USE AN IMPACT 3. Lubricate the block adapter o-ring and install the CP3 assembly. You will reuse the bolts that held the CP4 in place to hold the CP3 in place.
