The ZZP 1.4 turbo PCM brings the performance of your car to a whole new level. This is not a mail order tune, each ZZP tune is remotely tuned based on each customers car, mods, and octane. This is the best tune available in the market. We go through and rework dozens of tables based on countless dyno tuning with our own vehicles. We own 8 Sonics and a Cruze enabling us to dial in our tuning better than any other company in this market. Air Fuel ratios are optimized, boost is increased, timing is remapped, rev limiter is raised, and KR recovery is optimized. We do most of our work in torque management where these vehicles greatly limit performance and horsepower. By altering these tables, we unlock the full potential of the engine. We will start the boost around 16psi on the stock turbo, and the boost will end up between 15 and 19 psi based on scans from you, the customer. There are some tunes, that have users seeing spikes as high as 21+ psi, but we can assure you, they are not making more power, the vehicle is not safe on pump gas and the boost fades with RPM.
Octane note: Yes, some GM techs have said that you can run 87 octane in the 1.4 liter turbo, this is not true. We DO NOT recommend this, the car will have a lot of KR ("Knock Retard" or more commonly known as spark knock). By special request we have done specific tunes that make it safe to run lower octane, but performance will not be the same as running premium.
Gains of this tune paired with our intake are larger than anything else in the market. The best part about buying a ZZP tune is the support and fast responses you get. No one else comes close when it comes to expertise and speed of response.
We can also tune your 1.8 NA Chevy Sonic or Chevy Cruze. Just purchase the appropriate year and transmission option down below and we can complete remote tuning with you.
Core Charge: Our PCM flash requires a HPTuners programming interface and cable which we supply with instructions. Upon returning this cable, you are refunded the core charge (deposit). Additionally a Windows based laptop is required. you can use your own or borrow one from us. The advantage of using ours is that it is pre-configured with scanning software and tools to help us assist you if you have any questions or custom tuning requirements. If you choose to keep the tuning interface and/or the laptop, that's fine. That core charge will be adjusted based on what you keep. Core charges are based on 10 days and there will be additional charges if cables or laptops are kept for longer periods. After 30 days, core charges convert to purchases. Prepaid labels are only included with our domestic shipments. If you would like to watch a video to see how remote tunes work. Click here. HPTuners interface comes with the appropriate amount of credits to license your car.

If you are having knock (KR) related problems during your remote tuning sessions we recommend using Boostane. Boostane is a safe octane booster that actually works, unlike the generic "octane boosters" found at your local auto parts stores. We have noticed large spikes in fuel inconsistency since the beginning of the pandemic, so sometimes it's hard to point out if there's an issue with the car being knock limited or just the quality of fuel. While tuning if you add Boostane and notice the KR subside, then your problem lies in your fuel. If you add Boostane and it has no noticeable effect on KR, then it is likely that your car has a mechanical issue that is causing and/or being sensed as knock.
This 1.4 turbo tune is intended for 2012-2020 Chevy Sonic, 2011-2019 Chevy Cruze, 1.4 turbo Chevy Trax, Buick Encore, and Vanderhall Venice. As well as 1.8 NA Chevy Sonic and Chevy Cruze.
