FLOW CHART: Flow-matched sets are sold with a complete and unique flow-data chart indicating individual tested static flow rates at 3.0, 3.5, and 4.0 BAR. As well as 3.0 BAR dynamic pulse testing for idle, 15% duty-cycle and 50% duty-cycle. Along with a complete dead time off-set (latency) table. Flow testing was done with industry-standard equipment of the highest quality. The tests were performed at varying temperatures to achieve realistic results. Linear tuning with excellent low-end, and idle rpm. Fiveo is the only fuel injector seller that can claim this level of technology.

SPECIAL NOTE TO OUR E85 USERS: Ethanol based fuels tend to "dry" the fuel injector outlet orifices. Users/tuners should be made aware that this may cause a "sticking" problem in fuel injectors that sit idle for a prolonged period of time. It is suggested for applications running high ethanol content based fuels, to periodically incorporate into their fuel-system-maintenance a drop of light petroleum-based lubricant for each fuel injector. This is also considered to be good maintenance, but not essential, for stainless steel based (Black-Ops Series) fuel injectors. It should also be noted that for optimum performance the entire fuel system should be made up of ethanol approved materials including all fuel lines/fuel pump/fuel filter, etc.
