FAQ
Is DF-220-5G overkill for a stock LML?
DF-220-5G is intended for high-horsepower or future-build trucks. For stock or lightly tuned setups, consider the DF-100-5G or DF-165-5G listed above.
Does this work with CP3 conversions?
Yes. The stable, adjustable pressure and high flow support CP3 conversions and aggressive tuning when properly set up.
Where do I find installation instructions?
Use the official AirDog resource hub here: pureflowairdog.com/resources. Select the Duramax II/II-5G manuals for 2015–2016 applications.
What pressure should I run?
Most LML builds are happy in the 8–15 PSI base range; higher boost and fueling may warrant different settings. Always verify with your tuner/build plan.
