Propane Injection Boosts Pickup Power
Need more power and torque from your diesel engine when the going gets tough? Diesel Propane Injection (DPI) may be the answer. It's a closed loop ECM (engine control module) that injects propane as needed into a diesel fuel system, such as when pulling a load uphill.
Introducing the propane creates more power and torque. It works like the addition of nitrous oxide in a regular gas engine, explains a company spokesman.
The system was created by MSD, a company known for performance and racing components and is marketed by a subsidiary called Superchips. DPI systems are programmed for each application, so no customization of the existing fuel system is needed, no jets drilled or external adjustments required. GM DuraMax, Ford Powerstroke or Dodge Cummins each require a specific kit designed for that engine.
Kits come with detailed instructions, but the company recommends taking them to a certified dealer, especially to have the propane tank installed. Installation should take no more than an afternoon.
The closed loop ECM can be programmed to kick in at a certain rpm or boost pressure, but is never always on or always off unless disabled by manually flipping the switch on the system. The system also logs engine parameters for monitoring system performance.
A DPI system for a 2003 Chevy CK3500 Duramax 6.6LB7 sells for $1,040.
