Frequently Asked Questions
Is this a true bolt-on upgrade?
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.
What model years does it fit?
Confirmed for 2014–2019 LWN Duramax. Earlier builds (~06/2012–2013) can also be compatible — confirm by matching GM part number 94714569 or message us with your VIN.
Do I need a tune after installing?
No tune is strictly required for fitment. However, tuned vehicles will benefit most from lower IATs and reduced heat soak. Always monitor boost and EGTs on performance setups.
What boost is it rated for?
The FLEX monoblock core is rated to 80 PSI. Final safe boost depends on your overall setup (turbo, fueling, clamps, couplers) and quality of installation.
Will it work with my existing piping?
Yes — it’s designed around OEM routing. Aftermarket piping kits that relocate outlets may need minor adjustments.
What’s the typical lead time?
Items in Thailand stock usually dispatch within 2–3 weeks on pre-order. If you’re on a deadline, contact us before purchase for the current ETA.
