2001-2004 LB7 Duramax Reman Exergy SAC Injectors 400% w/ Internal Modification

So, you've made some power but now you want more? Do you still want good drivability while running more competitive events? Well, look no further than Exergy's 400% over fuel injectors!

The factory nozzles are swapped with a SAC type nozzle for its superior flow characteristics with the same spray pattern as factory. The nozzles are enlarged using inhouse micro EDM (Electrical Discharge Machining) and abrasive flow honing technology to achieve a matched set that hydraulically flows within 1%. Each nozzle undergoes six separate quality control checks throughout the process before being installed back onto the injector. All components are built and tested on specialized equipment designed and built in-house at Exergy. Every 400% over injector set is tested at multiple calibration points, balanced to +/- 1%, and shipped with a detailed sheet. There are no shortcuts.

Custom tuning will be needed to take full advantage of these injectors.

Core Return: Exergy requires that all cores be returned within 30 days from original purchase of product. If you fail to return the core(s) within 30 days, you will be charged in full for the core(s) ($150 per injector). Cores that have missing and/or damaged component(s) will not receive credit.
