Remote Tuning Service - 1999-2013 GM Trucks and SUVs

Revive and maximize the performance of your classic 1999-2013 Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, or other LS-powered GM trucks and SUVs. Our professional remote tuning service offers custom calibrations for Gen III/IV LS engines (including 4.8L, 5.3L, 6.0L, 6.2L variants like LR4, LM7, LQ4, LQ9, LS2, etc.) — perfectly tailored to your modifications, from stock to fully built setups.

Key Benefits:

• Substantial Power Gains — Unlock impressive horsepower and torque increases (often +30-100+ HP/TQ depending on mods like cams, headers, intakes, superchargers, or turbos), with sharper throttle response and optimized air/fuel/timing curves for reliable, streetable power.
• Improved Transmission Tuning — Firmer, quicker shifts on 4L60E, 4L80E, or other automatics, refined shift points, and torque management adjustments for better drivability and performance.
• DOD/AFM Disable — Fully disable Displacement on Demand (DOD) or Active Fuel Management (AFM) on applicable engines for consistent full-cylinder operation (ideal with or without mechanical deletes).
• Convenient Remote Process — Using HP Tuners MPVI2/MPVI3 interfaces, we provide base tunes and unlimited revisions via email data logging. No ECM shipping or dyno required — tune from home with minimal downtime.
• Custom Features — Gear/tire size calibrations, rev/speed limiter adjustments, E85/flex-fuel support, cold start improvements, fan settings, and full optimization for LS swaps or engine upgrades.
• Emissions Compliant Options — Performance tunes available that retain factory emissions components where needed for legality.

Perfect for daily drivers, tow rigs, off-road builds, or high-horsepower monsters. Our experienced tuners specialize in LS platforms, ensuring safe, data-verified results backed by years of proven expertise.
