Unlock the full performance potential of your 2024–2026 Chevrolet Silverado 2500 6.6L L5P with Lukos Engineering’s expert ECM and TCM tuning services. Designed for customers who want stronger performance and improved drivability, our calibration solutions deliver increased power, sharper throttle response, optimized torque delivery and smoother transmission behavior - all developed with reliability in mind. The 2024–2026 platform uses the E42 Global B ECU and T93 Global B TCM, and we can unlock and tune both modules in house for a complete engine and transmission solution. Our tuning is compatible with HP Tuners credits, requiring 8 credits for the ECM and 4 credits for the TCM, with potential gains of up to 110HP+. This allows us to optimize both engine and gearbox strategy together for the best possible result.
