Remote Tuning Service for 2014-2019 GM Trucks (L83 5.3L & L86 6.2L Engines)

Unleash the hidden performance of your 2014-2019 Chevrolet Silverado or GMC Sierra with the proven L83 5.3L or L86 6.2L Gen V V8 engine. Our expert remote tuning service provides custom ECU calibrations optimized for your specific mods, driving needs, and fuel preferences — all done remotely with no need to ship your ECM or visit a dyno.

Key Benefits:

• Impressive Power Gains — Unlock substantial horsepower and torque increases (typically +30-50 HP/TQ on premium fuel for tuned setups; even more with bolt-ons like intakes, exhausts, or cams), sharper throttle response, and better overall drivability for towing, daily use, or performance driving.
• (Optional Add-On Transmission Tune - Requires add'l tuning credits)Refined Transmission Tuning — Firmer, quicker shifts on 6-speed or 8-speed automatics, eliminating lag and improving shift points for a more responsive feel.
• According to HP Tuners - T87A unlock is no longer required (This send-in service is no longer required! Users can now simply license and tune their T87A TCM without any upgrade. Normal vehicle licensing still required)
• AFM/DOD Management — Fully disable Active Fuel Management (AFM) / Displacement on Demand (DOD) via tuning for reliable full-time V8 operation, or refine it to minimize issues while preserving efficiency (full mechanical delete supported with appropriate mods).
• Hassle-Free Remote Process — Using HP Tuners tools (MPVI2/MPVI3 interface required), we deliver base tunes and unlimited revisions for minor modifications through email data logging. Tune safely at home with no vehicle downtime.
• Custom Adjustments — Speedometer/gear/tire calibrations, rev limiter adjustments, top speed limiter removal, improved part-throttle efficiency, and support for E85/flex-fuel conversions where applicable.
• Emissions-Friendly Options — Stay compliant in restricted areas with performance-focused tunes that retain factory emissions equipment.

Ideal for bone-stock trucks or heavily modified builds (headers, cams, superchargers, etc.). Our tuners specialize in Gen V LT engines, delivering safe, reliable, and data-verified results based on years of proven experience.
