This product is for customers that have already purchased our ZZP LTG 1.0 pcm and need a basic file update for their ATS, CTS, or 2.0 Camaro. For example, you changed your injector size, changed cam(s), swapped to a different style MAF, changed gears in transmission, etc.  This simple update only applies to ZZP related file updates.  If you have a custom sheetmetal intake, custom turbo kit, or something similar that requires a lot of custom tuning, there will be additional charges.

PCM updates do not come with tech or tuning support.

• If you selected "I am sending in my PCM core" ship the core to the address below with a detailed note including your name, order #, and a complete mod list.
• If you selected "Email me a file" that means you have HPTuners already and then you will email Matt@ZZPerformance.com your file along with your complete mod list, order number, and we will modify your file and email it back to you.

Ship PCM cores to:

ATTN: (Enter order #)
ZZPerformance
2450 28th Street SW
Wyoming, MI 49519

*If you order products along with this, everything will be held until the PCM arrives and is reflashed for shipping.
*If you do not include a detailed note with the PCM it will delay your order.

*If you have a 2016+ car you likely will have to purchase credits to re-license the PCM if choosing sending in core first. If you have any questions about this process or how many you'll have to order please email customerservice@zzperformance.com
