Late Model GM Tuning — Consulting and Training:

Rios Racing provides specialized consulting and hands-on training for late-model GM vehicles, focusing on performance tuning, drivability, and reliability. Our services are aimed at professional tuners, race teams, performance shops, and serious enthusiasts who want to extract maximum, repeatable performance from modern GM powertrains while maintaining safety and longevity.

What we cover

• Component selection: We all have seen those guys that pic all the parts the internet says they should have but they don’t work together, or have the supporting mods required, then they do not perform like they should. Don’t be that shop with heads and cam customers getting outrun by one of our bolt on customers. learn how to pick the right parts the 1st time.

• Calibration fundamentals: we go over understanding GM engine control architecture, Air, fuel, spark, boost, nitrous system, closed-loop vs. open-loop behavior, and adaptive learning systems for optimal performance on the street, or track.

• Advanced calibration practices for high horsepower applications

• Forced induction: boost control strategies, wastegate vs. electronic boost control, target boost mapping, safety limits, cylinder pressure management, and tuning for transient response.

• Fuel system and injector scaling: injector characterization, high-flow fuel pump integration, fuel pressure control, and ensuring safe AFR targets across load and RPM.

• Transmission and driveline calibration: torque management, shift strategy, lockup torque converter tuning, clutch and line pressure adjustments for automatic transmissions.

• Emissions and OBD compliance: understanding OBD-II readiness, closed loop operation, sensor diagnostics, and strategies to maintain compliance where required.

• Data acquisition and analysis: the best practices, tips, and tricks for logging, and interpreting the data, fuel trims, lambda, timing, and transient events; using logs to iterate calibrations quickly.

• Safety and component protection: knock detection and mitigation, over boost protection, temperature-based safety features, and failsafe strategies.

• Hardware integration: sensor calibration, throttle body, camshaft and valvetrain upgrades, intake and exhaust tuning, and ECU hardware considerations.

• Vehicle-specific considerations: early genIII vs. late Gen IV/Gen V GM engines, coil-on-plug variants, drive-by-wire behavior, and common platform pitfalls.

• How to know when you’re getting bad data and how to pinpoint the problem to keep things rolling.

Training formats

• Private one-on-one sessions: custom-tailored for a shop or individual; theory plus live vehicle tuning and logging for hands on experience that sticks

• Group workshops: classroom modules paired with demonstration vehicles; ideal for team training or shop staff.

• Remote consulting and tune review: log review, calibration recommendations, virtual troubleshooting, and step-by-step guidance for implementation.

• On-site support: race weekend or project support including live tuning, and contingency planning.

Deliverables

• Actionable calibration changes documented with rationale.

• Logged before-and-after comparisons and performance metrics.

• Follow-up support for implementation questions and iterative refinement.

Who benefits

• Performance shops upgrading late-model GM vehicles.

• Race teams using GM powerplants in road, oval, or drag, drift, and burnout applications.

• Independent tuners broadening expertise on GM platforms.

• Enthusiasts building high-power street or track cars requiring reliable, daily-drivable calibrations.

Next steps Provide your vehicle details (Year, make, model, build details, current ECU platform (stock, reflashed, standalone), goals (HP/TQ targets, drivability priorities, or expected et), and whether you want remote or on-site support.
