Stop Guessing. Start Tuning Your Cummins.
Built for Dodge Ram Cummins trucks — 5.9L 12V VE, 12V P-pump, 24V VP44, and Common Rail. Reads your logs. Breaks down what the truck is doing. 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. It's helped over 267 people so far.
267+ Tuners Helped | 2+ Years Daily Use | Tested by Well-Known Tuners — Couldn't Break It
How It Works
Step 1 — Upload Your Log: Drop your Cummins log file in. No setup, no config. Works across all supported platforms — 12V, 24V VP44, and Common Rail.
Step 2 — AI Reads the Diesel Data: It reads boost, EGT, fuel pressure, rail pressure, injection quantity, turbo behavior, and transmission load — not guessing, reading.
Step 3 — Get Exact Direction: Know exactly what to adjust and which way to go. No more guessing at fueling, boost, or timing on your Cummins.
This is NOT ChatGPT
ChatGPT is a large language model. StreetTunedAI Cummins Edition is a custom GPT that's been trained to tune diesel trucks. It reads the actual data from your log and has safety limits built in.
What it will NOT do: treat smoke as a tuning goal — dump fuel without air — ignore EGT — overlook fuel supply issues — recommend power on a slipping transmission.
"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."
