This is a pre-prepared package of mods for your 2.0L ATS. It includes our PCM Tune, Cold Air Intake, and Downpipe. The tune will modify the factory PCM file for extra horsepower and performance, the cold air intake will decrease intake air temps and reduce inlet restriction, and allow you to hear the turbo whistle, the downpipe will free up exhaust flow for more horsepower. This package should give you an additional 60 horsepower over stock and you will lose nothing, in fact the car will run and drive even better than before along with better MPGs. Very easy install, it should take less than 2 hours to install the entire kit.  The tune that is included is not a "mail order tune" this is a full remote tune.  This means each customers car is specifically tuned for their mod, their fuel, etc.


  • Cold Air Intake
  • Downpipe combo

    Core Options

    • Sending in Core First: With this option you are going to send us your PCM from your vehicle. This route retains remote start since you will be using your original PCM. If you have a 17+ auto car you will need to get your TCM unlocked through HPTuners and send that in with your PCM. With this option your intake and downpipe will be held until we receive your PCM, then everything will be sent back in one shipment. This is not a cookie cutter "canned tune" as many online would make it seem, this is a ground up tune built around your modifications.

    • Send Me a Core: We can ship you a PCM core that is already flashed with our file.  The benefit of this, is that you can keep your stock PCM to reinstall if you need to bring your car in for warranty work.  The disadvantages are a: that if you have remote start, it will disable it. (This applies to 13-17 ATS, CTS) and b: if you have a '16+ manual trans car, you will have to go to the dealer and get a clutch relearn.

    • Rent/Purchase Interface and/or Interface & Laptop: This option is known as remote tuning. With this option you will receive either the HPTuners MPVI2 interface or the interface and laptop, based on what option you chose. Our tuner will then be in contact with you throughout the whole tuning process. You will read your stock file, send it in, which the tuner will then put together a base tune. You will then go out and data log the car and send that back to the tuner; they'll make revisions and send back. You will go back and forth until you're both satisfied. Our video on the remote tuning process can be found HERE. When tuning is done, you can return the interface/laptop, and you are refunded the interface/laptop core charge (deposit).  Since you are keeping your stock PCM core, this will retain your remote start feature.  If you do not rent our laptop, you will need a Windows based laptop to read/write your ECU.  The advantage of using ours is that it comes pre-configured with the tuning and scanning software required so you can simply charge the laptop, power it up and get started immediately. We highly recommend keeping the HPTuners interface as it's a great tool for data logging, clearing check engine lights, and if you ever want to re-tune down the road you do not need to re-credit with the same MPVI. 

    • I own HPTuners Email Me a File: This option is for customers who already own an HPTuners interface, and will follow our remote tuning process. You will still need to purchase credits to unlock your PCM and TCM if you have not done so. We sell credits HERE

    ZZP Flex Fuel Conversion Kit: No, not installed. Yes, Enable ZZP Flex Kit. - Do not select this unless you are installing this kit at the exact same time as the PCM. If you add the kit later you can order our PCM Update to enable the flex kit in the file later. NOTE: Flex fuel is available for all model year LTG's as of February 2020. 

    Cold Air Intake: If you are looking for an entire replacement intake tube and air box, here is our 2.0 liter LTG cold air intake. It is made of aluminum to keep it nice and lightweight. The air box will make sure that the air filter is drawing cool air in instead of hot under hood air. Very easy install, it will take around 15 minutes or less, no tuning required.

    Downpipe: This o2 housing bolts directly to the turbo's outlet and then bolts to the factory downpipe. It is 3" in diameter, an o2 bung for your factory o2 sensor, and 100% stainless steel. The outlet flange is tapped just like the factory o2 housing for ease of install, you will not have to deal with trying to hold the bolt when tightening the nut in the tight engine bay.

    Stage 2 kit here. It adds our Intercooler kit and catback exhaust to this kit making it a full Stage 2 car.

    If you select "sending in core first" send core to:

    Great quality and awesome customer service!

    Overall the quality and customer service for this product was great! I have a 2018 ATS 6 speed manual which required me to source my own clutch relearn otherwise my car would not function with the new tuned PCM which could cost anywhere from $50-$250 which was an unexpected charge for my specific car but overall the new parts fit great, sound great and look great! The turbo blow off is much louder and is so nice to hear! Coupled with their intercooler kit and their full exhaust system my car is sounding and running great! I’ve put about 2,000 miles on the car with no issues running 91 octane. Easy install other than one specific turbo/downpipe nut being hard to get to! I had it installed in alittle less than 45 minutes! Overall a great experience!

    Love it.

    Have Stage 1 and 2, larger throttle body. Denso plugs, ignition coil and tuned. Running 94octane for now. The elevation is 804 ft at the motorplex and the temperature was 70 deg and humidity 70 percent. The numbers look good, still room for some improvement. Some stats: 0-60 in 5.02 sec and 1/4 mile in 13.718 at 99.17 sec. The car was getting faster has the temperature was droping. I did get a lot of compliments on the performance of my 4 ****** :) The car stats on the left was from a supped up Aspen R/T. Now i need More POWER!!!!! Love what ZZP offers, next is the turbo.

    Really Wakes up the ATS

    I have the complete Stage 1 Kit on my 2015 Cadillac ATS coup and it really wakes up the car. Driving this car is like night and day. I also added the oil catch can as well. Turbo Tim was great to work with and really had my car dialed in after four revisions. The tuning process was very easy. Tim also recommended adding the Denso Racing plugs which I also added. The next mod is the intercooler which I have already ordered. If you are thinking about getting this kit do it. You will be glad you did.

    Highly Recommend As First Mod

    This was my first group of mods and I think its a good starting point. I would get an exhaust as well for a more complete package. Nothing bad to say really, but I did cut the air box after a while to be able to get to the MAF sensor easier tbh. Good parts, i remember it was like night and day difference, really woke the car up. Pretty easy install for these parts. Been running this and adding to it since 4/2019.....sorry for the late review.
