01 / WHAT WE DO

A tune starts with
understanding the build.

Tell us what’s under the hood, what’s changed, and how you want it to drive. We’ll discuss the right next step for your setup.

01

GM calibration

LS and Gen V tuning with HP Tuners. Calibration for cam and injector changes, drivability, and transmission behavior.

02

Holley EFI & swaps

Help with Holley EFI setups, engine swaps, startup, idle, and fuel and ignition calibration.

03

Find the actual fault

No-starts, poor running, and combinations that won’t cooperate. Diagnose the underlying problem before chasing the tune.

02 / A REAL DIAGNOSIS

Seven years.
One overlooked seal.

The owner had spent seven years unable to get this supercharged project running. Within an hour of getting involved, we had it running.

The culprit was an injector O-ring inside the blower hat, leaking unmetered fuel into the engine and flooding it. Fixing the fuel leak came first. Tuning followed at our previous California shop.

Good tuning starts with a mechanically sound engine.
Watch the project story

Seven years without running. An injector O-ring inside the blower hat was leaking fuel and flooding the engine. The leak was corrected, the engine ran, and tuning followed at the previous California shop.
