A Duramax problem can look like a tuning problem when it is really fuel supply, rail pressure, boost, heat, torque control, or transmission behavior.
DuramaxTunedAI is built to give you a knowledgeable second set of eyes on the data, like having a tuning assistant beside you while you work through the problem.
It helps review desired and actual rail pressure, VGT and boost behavior, smoke, heat, EGT, torque limits, fuel supply, and transmission clues before you start changing things just because a number looks wrong.
It supports LB7, LLY, LBZ, LMM, LML, LGH, L5P, and L5D applications. It is made for work trucks, tow rigs, street trucks, and higher power combinations where the log needs to lead the decision.
If the data points to a fuel problem, heat problem, turbo problem, transmission problem, mechanical issue, or missing data, that needs attention before chasing more power. That is the kind of answer that can save time and expensive parts.
DuramaxTunedAI is currently a separate workspace. An active ChatGPT subscription is required right now. I am in the process of moving these separate workspaces into the StreetTunedAI Tuning Portal.
The price is $74.99 for DuramaxTunedAI access.
