This 2018 Colorado came in for a manifold clean, DPF‑back exhaust, and a custom remap. After clearing out years of build‑up and dialing in the tune, it picked up from 108.7 kW to 133.8 kW on the dyno - see the graph for the before/after.
Cleaner breathing, better response, and a much happier Colorado all round.
