This product is for customers that have already purchased our ZZP 1.0 pcm for your LSJ, LNF, LHU, or 2.2/2.4 and need a basic file update. The update is available only to those who have purchased our 1.0 file, not to those who have a vehicle that they purchased that has been previously tuned by us. 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 sheet metal 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 LSJTuning@ZZPerformance.com (for LSJ), Matt@ZZPerformance.com (for LNF, LHU), or Adam.W@zzperformance.com (for 2.2/2.4) your file along with your complete mod list, order number, and we will modify your file and email it back to you.

*If you order products along with this, everything will be held until the PCM arrives and is re-flashed for shipping.

*If you do not include a detailed note with the PCM it will delay your order.
