Built for GM Duramax owners using HP Tuners or EFI Live.

Review rail pressure, VGT and boost behavior, smoke, heat, torque limits, fuel supply, and transmission clues before chasing the wrong limiter or subsystem.

$74.99 gets you access to the separate DuramaxTunedAI workspace. Digital access only — no shipping. This is separate from the LS/LT portal and does not use login.streettunedai.com. You need your own active ChatGPT subscription, purchased separately from OpenAI. Use the Duramax access link delivered after checkout to open the separate StreetTunedAI Duramax ChatGPT workspace.

What It Helps You Review

  • Desired versus actual fuel-rail pressure
  • VGT airflow control and boost behavior
  • Smoke, heat, EGT, and turbo-safety concerns
  • Torque-model and defuel conditions
  • Fuel-supply concerns and CP4-related warning signs
  • Transmission slip or torque-intervention clues

Built for Real Duramax Work

Supports LB7, LLY, LBZ, LMM, LML, LGH, L5P, and L5D applications. It is intended for stock work trucks, street builds, tow setups, and higher-power combinations where the log needs to lead the decision.

What Happens After You Buy

Important

DuramaxTunedAI is a separate ChatGPT-based product. It does not create LS/LT portal access and it does not use the LS/LT portal upload workflow.

It is built to stop power tuning when the data points to fuel supply, heat, turbo safety, transmission, mechanical, or missing-data problems that must be handled first.

Find the real limiter. Fix the right subsystem. Then tune safely.

What This Catches That People Miss

StreetTunedAI identifies tuning failures that don’t show up as obvious errors but cause endless chasing.

• Power Enrichment commanded but never actually activating
• Idle airflow tables mismatched to camshaft behavior
• Injector data copied correctly but applied to the wrong model
• Spark tables edited without verifying which table the ECU is referencing
• Boosted setups overshooting fuel on tip-in
• VE or MAF corrections made in the wrong operating region

These are logic problems — not missing parts.

Why This Tool Exists

StreetTunedAI was built because most tuning problems don’t come from bad parts or missing mods.

They come from logic errors:
– Tables being edited that the ECU isn’t actually using
– Features enabled on paper but not in operation
– Correct data applied in the wrong model
– Fixes made in the wrong operating region

This tool exists to identify those mistakes before time and parts get wasted.
