Performance Services
Nelson Performance specializes in GM LS and LT tuning, diagnostics, and performance upgrades for trucks, Camaro, Corvette, SUV platforms, and LS/LT swapped vehicles.
Data first. Tune second. We focus on finding the real issue, matching the calibration to the vehicle, and building performance setups that drive the way they should.
What We Do
GM LS/LT Tuning
Street tuning for GM trucks, Camaro, Corvette, SUV platforms, and LS/LT swapped vehicles. We tune for drivability, performance, transmission behavior, and overall vehicle setup.
Diagnostics & Drivability
Misfires, communication issues, fuel trims, wiring faults, sensor problems, idle concerns, and drivability complaints. We diagnose before throwing parts or blaming the tune.
DOD / AFM Deletes
Camshaft and lifter-related service for GM platforms equipped with DOD/AFM systems. We quote the correct supporting parts and calibration needs for the setup.
Cam & Performance Upgrades
Camshafts, pushrods, valve springs, headers, intake upgrades, power adders, and supporting performance work for LS and LT platforms.
LS/LT Swap Tuning & Diagnostics
Support for older vehicles and non-GM platforms with LS/LT swaps. We do not currently perform full conversion builds, but we do tune and diagnose swap-related issues.
Injector Cleaning & Flow Verification
Injector cleaning, spray-pattern inspection, seal replacement, and flow verification, including reverse-flow service when appropriate.
How We Work
- Diagnostics come first. A tune cannot fix bad data, wiring issues, fuel problems, or mechanical faults.
- Quotes are based on the vehicle and setup. Modifications, year range, credits, unlocks, and parts availability can affect pricing.
- Appointments are required. This allows us to plan work properly and give each vehicle the attention it needs.
