What we do for the c8 z06.

The LT6 is naturally aspirated, high-revving, flat-plane — a clean-sheet V8. Stage 1 maps on this platform are still being refined across the industry. We custom-tune every Z06 on our dyno from the customer's specific fuel + supporting mod combination. No off-the-shelf flash, no shortcuts.

Common questions.

Is there an off-the-shelf flash for the Z06?

Multiple vendors offer OTS files. We don't sell or install OTS on the Z06 — every halo platform we tune is custom on our dyno. The platform is too new and too valuable to flash a generic file.

How much power can the LT6 make?

On stock fuel + IC the LT6 is limited by the intake manifold geometry. Real numbers come from headers + custom map. We'll scope the full path on the call.

Does tuning affect the 8K RPM redline?

We respect the factory rev limit on initial tunes. Aggressive builds with valvetrain upgrades can extend it, but that's a separate conversation.

How long does the Z06 appointment take?

Full day minimum. Built-motor / forced-induction conversions are multi-day projects, scoped ahead.
