GM LS & LS-Swap Tuning with HP Tuners

Smooth drivability, strong throttle response, and verified power. We use HP Tuners VCM Suite to calibrate GM LS platforms and LS swaps the right way with data-logged adjustments on street and dyno.

HP Tuners Expertise

VCM Editor and Scanner workflow dialed for MAF, VE, spark, torque management, and idle control.

Data-Driven Results

High-resolution logs for fueling and timing corrections that improve response and repeatability.

Built For Your Combo

NA, boosted, cammed, or swapped. We calibrate around injectors, MAP, gear, tire, and fuel type.

Street & Dyno Validation

On-road drivability checks and optional DynoJet 2WD sessions to verify HP, TQ, and AFR.

Safe, Repeatable Tuning

Knock monitoring, conservative baselines, and step-by-step changes for reliable gains.

Supported Platforms & How To Prepare

  • GM LS platforms and LS swaps with OBD-II ECMs supported. Drive-by-cable and drive-by-wire welcome.
  • Please bring your HP Tuners MPVI device and ensure you have credits available for your ECM/TCM if required.
  • Arrive with quality fuel, no leaks, good plugs, proper tire pressures, and a healthy charging system.

Baseline & Scan

Initial health checks, DTC review, and baseline log to identify fueling, timing, and idle needs.

Fueling & Airflow

MAF and VE calibration, injector data entry, PE/BE targets, cold start, and transient fueling.

Spark & Torque

High/low octane tables, knock strategy review, torque management, and throttle response refinement.

Idle & Drivability

Idle airflow and timing, cammed-engine stall fixes, dashpot, DFCO, gear and tire calibration.

Session Details

Sessions include pre- and post-logs with saved tune files. Dyno time is available for power validation and safe boost tuning. Certain modifications may require additional credits. Tuning is performed in accordance with applicable laws.

Optional wideband integration available when equipped. We can retune after hardware changes like injectors, camshaft, or forced induction upgrades.
