Your crew chief.
In your pocket.

TuneChief reads the air, calls your dial, analyzes your Holley datalogs, and finds the money races — no laptop, no $2,000 weather station.

🎧 THE CHIEF
How it works

From the lanes to the win light

STEP 1

Read the air

Live weather for any track — density altitude, water grains, and air density, corrected for elevation. No hardware.

STEP 2

Get the call

The AI Chief knows your car, your runs, and your setup. It predicts your ET and MPH, calls your dial, and tells you what to change between rounds.

STEP 3

Turn on the win light

Log the pass with the air and shock clicks snapshotted automatically. Every run makes your next prediction sharper.

What's inside

Everything the big trailers have. None of the hardware.

🎧

AI Crew Chief

Ask it anything, in plain English. It answers with your car, today's air, and your run history in mind.

📊

Holley datalog analysis

Upload your CSV log. It reads AFR, IAT, timing, and knock — and tells you what happened on the pass.

💰

Purse race alerts

An agent scans your tracks' schedules and flags races with money on the line before you'd have heard about them.

🏁

Race day mode

Round-by-round logging, live win/loss record, and air-drift dial calls between rounds.

🎯

Predictions & dial-in

ET and MPH prediction that learns your car from your own passes, plus a dial-in with your safety pad.

🔧

Full setup logbook

Shocks, ride heights, weight split, boost ramp — snapshotted onto every run so you can see what worked.

Pricing

Less than one entry fee. All season long.
