These injectors start as brand new OEM Hitachi fuel injectors. Then they are modified to flow 50% more fuel than stock, flow tested and matched in sets to flow within 0.5% of each other. They maintain stock idle characteristics, are perfectly linear and remain rock solid, even at 3,000 psi! These injectors provide drop-in fitment, with no adapters or pigtails required.
Every Xtreme-DI fuel injector set gets tested and matched at three different operating points and comes with full documentation:
– 0.8 ms. @ 290 psi (20 bar) for idle stability
– 10.0 ms. @ 1,450 psi (100 bar) for static flow reference (qstat)
– 6.0 ms @ 2,900 psi (200 bar) for WOT performance and stability
Please note that custom tuning is required for these fuel injectors. Tapout Tuning is the premier LF4 tuner worldwide, and we will be happy to help in this area. You can find more details on our Remote Tuning services for the ATS-V and CT4-V Blackwing at the links below:
