Need more power, better shift points, or just want to turn off annoying check engine lights? I offer custom GM ECM/PCM computer tuning for all 1999 to 2007 Chevrolet and GMC trucks, SUVs, and cars (Silverado, Sierra, Tahoe, Yukon, Suburban, Corvette, Camaro, etc.).Safe, reliable custom tunes using professional software. Whether you need a simple software tweak or a full performance street tune to wake your vehicle up, I can handle it.High-Demand Specialized Services:VATS Delete: Complete Vehicle Anti-Theft System bypass. A must-have to get your engine starting for budget LS swaps into hot rods, older trucks, or square bodies.Torque Management Removal: Eliminate the factory throttle lag for instant pedal response, crisper acceleration, and a much faster-feeling truck.DOD / AFM Delete: Electronically disable drop-cylinder Active Fuel Management to protect your lifters from mechanical failure and keep your engine in V8 mode 100% of the time.Custom Transmission Tuning: Firm up soft, sloppy shifts on 4L60E and 4L80E transmissions. Greatly improves driving feel and protects your clutches while towing heavy loads.Gear & Tire Calibration: Fix inaccurate speedometers and correct factory transmission shift points after installing lift kits, bigger tires, or swapping rear-end gears.Standard Fixes & Code Clears:Lower electric fan activation temperatures to keep your engine running cooler under heavy load.Turn off unnecessary check engine lights causing limp mode (EVAP, rear O2 sensors, EGR deletes).Remove factory speed and RPM governors/limiters.Optimize fueling and spark advance maps for upgraded camshafts, intakes, or exhaust systems.Send me a message with your vehicle's year, model, engine size, and a list of what you want done, and I will get back to you with a more detailed quote! below is a list of cost I do discount for multiple services. I DONT NEED THE VEHICLE IN MOST CASES! Just the PCM!!

$50 – Single Quick Fix: Basic speedometer recalibration for tire/gear changes, or adjusting electric fan activation temps.
$75 – Standalone / Swap Preparation: Complete VATS (Anti-Theft) delete, emissions code deletes (EVAP/O2/EGR), and speed limiter removal for project cars and LS swaps.
$100 – The "Drivability Bundle": Torque management removal (fixes throttle lag) combined with custom transmission shift tuning for 4L60E/4L80E (firmer, better shifts for towing/street).
