FAQs
Does this system require custom tuning?
Some retailers note “Super Extreme – Requires Tuning” for certain Plus systems. Verify your current calibration and supporting mods; many L5P builds over stock fueling will benefit from a matching tune.
What filters does the Titanium Signature Series Plus use?
It uses a 2-micron fuel filter and a dedicated water separator. Follow FASS service intervals (typically ~30,000 miles) or sooner in harsh conditions.
Will it reduce injector failures?
By removing air/vapor and water while polishing the fuel, the system helps protect injectors and high-pressure pumps compared to factory-only filtration.
Is the system loud?
The Plus pump uses FASS Whisper Technology to operate very quietly without sacrificing flow.
