Every review comes back structured, not improvised

• Action First. Safety check before anything else. Hard-stop conditions appear at the top, in red.
• What I Received. A table of what was Confirmed, Suspect, and Missing. You see exactly what the analyzer worked with.
• What I See. Plain-English read of fuel trims, KR, MAF behavior, airflow, and load.
• Confidence by Section. Separate scores for Channel ID, Fuel Trim, WOT, Knock, and Startup. One overall score would be a lie.
• Fuel Trim Analysis. STFT, LTFT, whether LTFTs have learned, whether STFT is carrying load.
• MAF Hz Correction Suggestions. By Hz range, with sample-coverage suppression. Bins under 100 samples get suppressed.
• Knock / Spark Review. KR by RPM range, exact cells to pull timing from, and a reminder to verify Interpolate is OFF.
• WOT / Power Enrichment. With explicit blockers if the log cannot support a safe edit.
• Do Not Touch. The list of what NOT to change from this log. This is the list that saves motors.
• Next Log Plan. A specific plan so you keep moving, not guessing.
• Bottom Line. The honest summary.

Every report downloads as a PDF. Every report saves to your vehicle's history.

Three workflows in one portal

1. Your vehicle already runs. Start with Start My First Log. The portal walks you through channel setup, VCM Scanner logging, CSV export, and your first upload.
2. You built a new combination. Use Startup Builder. Describe the engine, cam, injectors, controller, transmission, induction, and current tune values. Get conservative first-start direction before you crank it.
3. You have two tune files. Use Tune Compare. See exactly what changed between a base tune and a modified tune. Stops the "what did I change" chase cold.

After you buy

1. Complete checkout at $74.99.
2. Go to https://login.streettunedai.com
3. Register with the same email you used at checkout.
4. Open Start My First Log and follow the setup.

What you need

• An LS or LT-powered vehicle or project
• HP Tuners VCM Suite or EFI Live, plus your logging hardware
• A laptop for VCM Scanner logging and CSV export
• Internet access for the portal

Wideband is optional for idle, cruise, and drivability review. Required for WOT fueling direction. This tool will not pretend otherwise.

What StreetTunedAI does NOT do

• Does not write or flash tune files
• Does not replace a wideband with narrowband data
• Does not treat missing data as proof
• Does not connect to your MPVI, drive your vehicle, or physically verify mechanical condition
• Does not guarantee a mechanical problem is a tuning problem. It will tell you to inspect the truck first when the data points that direction.

Why every review says the same thing

Look at any review of this tool. They all say variations of the same three things: it explains why changes are needed, the log review is thorough, and Bryan answers messages personally. That's not marketing. That's the product.

Ward Specialty Performance called us "the tip of the spear" for tuners learning systematic tuning. Real professional shops use this tool. So do first-time HP Tuners owners. So do experienced tuners who want a second set of eyes.
