❓ Frequently Asked Questions

Q: Is this a true bolt-on upgrade?

A: Yes — designed as a direct replacement for RG Colorado LWN 2.8L. No cutting or welding required when used with factory mounting and pipe locations.

Q: What model years does it fit?

A: Confirmed for 2014–2019 LWN Duramax. Earlier builds (approx. 06/2012–2013) may also fit — confirm by matching GM part number 94714569 or send us your VIN.

Q: Do I need a tune after installing?

A: No tune is required for fitment. Tuned vehicles benefit most from lower IATs and reduced heat soak. Always monitor boost and EGTs.

Q: What boost is it rated for?

A: The FLEX monoblock core is rated to 80 PSI. Final safe boost depends on clamps, piping, turbo setup and tune quality.

Q: Will it work with my existing piping?

A: Yes — designed around OEM routing. Aftermarket piping kits may require minor adjustment.

Q: What's the typical lead time?

A: Generally in stock in Australia, but from time to time item dispatch may be up to 2–3 weeks. Contact us for current ETA if timing is critical.

Q: What's the advantage of monoblock construction?

A: One-piece monoblock casting provides superior strength and reliability under high boost compared to multi-piece designs. Less prone to leaks or failure.

Q: Will this improve my performance?

A: Cooler intake air temps mean denser air charge, which supports more consistent power output, especially on tuned vehicles or under sustained load (towing, highway runs).

Q: Do I need to upgrade my clamps or piping?

A: For high-boost applications (40+ PSI), consider upgrading to quality silicone hoses and heavy-duty T-bolt clamps for maximum reliability.
