Fits 2006-2007 Chevy/GMC 2500/3500 HD LBZ

Part# E01 10308

The 100% over Injectors are remanufactured and then honed and balanced to the desirable flow rate. These 100% over injectors should be installed in trucks with turbo upgrades and tuning. At this level of injection, upgrading to dual CP3 pumps with modified pumps as well a lift pump is required. 

Once the nozzles are opened up to the desired flow percentage, then the injector is reassembled and the set is balanced to within +/- 4%.

  • What size injector should I be looking at?

    We always recommend contacting us directly so we can go over your build with you and come up with the ideal setup. Below is a outline of some basic information regarding injector sizes.

    Exergy 20-30% Over Injectors:

    This is our number one selling injector size due to price and functionality. This is a great upgrade from stock when your injectors need replacing and will work great with a factory CP3 pump. We always recommend the addition of a lift pump, but at this level isnt required. A 20-30% over injector will have a flow improvement that will help with fuel economy and throttle response. When properly tuned, engine longevity will be increased due to the reduction in pulse width and timing. Also, most of the smoke normally associated with bigger injectors can be cleaned up and the truck will still run as clean as stock.

    Exergy 40-60% Over Injectors:

    Injectors with 40-60% increase are great for guys with a moderate turbo upgrade. This level is probably on the large side for a factory sized turbo but can be used with them. Proper tuning will go a long way with larger style injectors as aftermarket box tuners will no longer be adequate. When using injectors in this size range, you should have a lift pump setup on your truck. Running twin CP3s or a least a modified injection pump is recommended for ideal performance.

    Exergy 70-100% Over Injectors:

    Injectors with a 70-100% increase are great for those running larger single turbo or compound turbocharger applications. Generally used in drag racing or sled pulling applications but can be streetable with proper tuning. At this level, you will NEED to have a modified stroker CP3 pump or twin CP3s as well as a lift pump to properly supply these injectors with enough fuel.
