Stop Guessing. Start Tuning Your Duramax.
Built for GM Duramax platforms — LB7 through L5D. Reads your HP Tuners or EFILive logs. Breaks down what the truck is doing and tells you exactly what direction to go — no guessing.
I've been using it daily for about 2 years now and it turned into something that's actually really solid. Trusted by 400+ tuners and enthusiasts.
Trusted by 400+ Tuners and Enthusiasts | 2+ Years Daily Use | Tested by Well-Known Tuners — Couldn't Break It
How It Works
Step 1 — Upload Your Log: Drop your HP Tuners or EFILive log file in. No setup, no config.
Step 2 — AI Reads the Diesel Data: It reads fuel rail pressure, VGT response, EGTs, boost, and transmission data from the log — not guessing, reading.
Step 3 — Get Exact Direction: Know exactly what table to touch and which way to go. No more guessing at smoke limiters or torque models.
This is NOT ChatGPT
ChatGPT is a large language model. DuramaxTunedAI is a custom GPT that's been trained to tune diesel. It reads the actual data from your log and has safety limits built in — fuel-supply checks, CP4 protection, EGT limits, boost-stability checks, turbo-speed safeguards. If the data don't support changes, it won't give them.
"I've had a few well known tuners test it and try to break it and they couldn't get it to give bad info."
