Before we turn wrenches or upload new maps, we perform essential diagnostics to understand your vehicle's current health and baseline performance:

  • 🔍 Engine Health Scans - Comprehensive ECU readouts to check for fault codes, system readiness, and sensor status
  • 🛠️ Compression & Leakdown Testing - Verifies internal engine integrity before performance upgrades
  • ⚡ Electrical & Charging System Checks - Ensures stable voltage, battery health, and wiring integrity for reliable tuning
  • 🌡️ Fuel System Diagnostics - Confirms fuel pressure, injector performance, and delivery consistency
  • 💨 Air/Fuel Ratio Baseline Logging - Captures real-time AFR data to inform accurate tuning decisions
  • 📊 Baseline Dyno Testing - Measures horsepower, torque, and drivability to establish your starting point

These diagnostics aren't just technical, they're strategic. They help us tailor every build and tune to your vehicle's needs, so performance gains come with peace of mind.

Please Note: In Shop/ Over the Phone Diagnostic Services start at $135 per hour. Once you have been scheduled, you will be emailed an invoice to pay prior to Diagnostic Services taking place.

If your vehicle is already in the shop with us, Diagnostic Charges will be transferred to your current build/ tune invoice.
