If you're looking for increased performance or fuel economy, Exergy's REMAN or NEW fuel injectors should not be overlooked. 

All injectors are calibrated on genuine Bosch equipment in actual conditions. You will receive a full analysis as well as a calibration sheet that lets you know exactly how the injector flows at idle, part throttle conditions and WOT conditions. These are not just a run of the mill aftermarket nozzle thrown on an abrasive hone machine and put in box. Exergy will go the extra step to provide the up most quality which will equate to a better, smoother and more efferent running engine.

Once the nozzles are opened up to the desired flow percentage, then the injector is reassembled and the set is balanced to within +/- 5%.

Cores

To help insure inventory levels and keep the costs low, Exergy assigns $150 refundable core charge per injector that will be applied to your order during checkout. Cores must be free of mechanical defect, damaged injector bodies, stripped threads, excessive rust/corrosion and match the model you ordered. In the event you'd like to avoid the core charge, please check the box "Return Core First". This will hold your order until your core is received.

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. Larger is NOT always better! Smoke is typically a byproduct of unsatisfactory tuning, not power. Below is a outline of some basic information regarding injector sizes. Please keep in mind, oversize injectors require tuning for proper A/F ratio. DHD does not offer these services. Any charges to your trucks fuel system may result in the inability to pass government administered emission testing. DHD does not recommend installing oversize injectors in ANY licensed on road vehicle.

Exergy Sportsman-45% 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 isn't required. A 45% 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 60-100% Over Injectors:

Injectors with 60-100% 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 150-500% Over Injectors:

Injectors with a 150-500% increase are great for those running large single turbo or compound turbocharger applications. Injector of this size are generally used in drag racing or sled pulling applications. 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.
