What’s Included:

• Custom base tune tailored to your engine & transmission setup

• Bench flash of your stock GM PCM (P01/P59 – 1999–2007 LS)

• Tuning for 4L60E, 4L80E, or manual transmission setups

Tune Disclaimer:
This is a custom base tune designed to get your engine running, idling, and moving under its own power. It is intended to help you start the engine, verify proper wiring, mechanical setup, and ensure your swap is electronically sound before driving.

While this tune should make the vehicle drivable, further tuning may be required to dial in fuel trims, wide-open throttle, boost, or other performance-critical areas. We do not offer datalogging or remote revisions. All fine-tuning must be performed in person by a qualified local tuner if needed.

Requirements:

• You must send your physical PCM for tuning

• A tuning form will be emailed to you after purchase and must be completed before work begins
