Frequently Asked Questions

Q: Do I really need ECM programming if I’m swapping to a single turbo?

A: Yes — the factory ECM settings are designed for the twin-turbo setup. Without tuning, your engine will not run properly and could face performance or reliability issues.

Q: Can I use my old 18:1 pistons with the new single turbo?

A: We do not recommend it. The 16:1 pistons are engineered for lower compression, allowing you to safely run higher boost levels without engine knock or failure.

Q: Is this kit compatible with all C15 Acert engines?

A: Yes, it fits MXS, NXS, SDP prefixes with 120 PIN ECMs and BXS prefixes with 70 PIN ECM. We’ll help you choose the correct ECM programming for your build.

Q: What’s the difference between the turbo stages?

A:

• Stage 1 – Stock replacement, reliable performance

• Stage 2 – Slightly increased flow and boost

• Stage 3 – Great for towing, more power and responsiveness

• Stage 4 – High-performance build, aggressive fuel and air tuning
