Basic programming service to reflash your ECM to a 100% stock tune. All programming is done with a Tech 2, not EFILive, so you are guaranteed to get a fresh tune with all of the latest GM updates, just like new.

If you have a "locked" ECM that was previously tuned, we can overwrite this tuning and return the ECM to a stock "unlocked" tune.

Turnaround time is 1 business day, or we can also do an ECM core-exchange if you can not have your truck down. Buyer pays shipping both ways for ECM. Core charge applies, and will be refunded upon receipt of your working/good condition ECM. Core charge is NOT included in the price!

NOTE: If you send us an ECM that has badly broken connectors, is damaged physically, or has been "bricked" by a bad tune or tuner reflash gone wrong, the core charge will NOT be refunded!!
