SCHMIDTY TUNING PACKAGES: 

We can tune the cars with no mods at all, just a set of plugs as well
however the recommended parts below entail the best "Bang For Your Buck" as we ramp up the power & performance of your ATS-V or CTS V-Sport
 

STAGE 1  

With this package an ATS-V has the potential to run drag passes ranging from high 10 seconds to mid 11 seconds in the ¼ mile while producing around 

500 RWHP give or take depending on the dyno.

2. Drop in KN Filters - Click Here

Schmidty Flex Fuel Tunes 

The stock ATSV fuel system can be tuned with a roughly E30 blend.  The CTS Vsport can handle a bit more, usually in the E35-E40 range however if you want to run more boost and higher ethanol content you need to upgrade the fuel systems.  Flex fuel tunes require a flex fuel sensor.

  STAGE 2  
Known as our famous "Grey Sweatpants Package" an ATS-V can be expected to run anywhere from high 9 seconds to mid 10 seconds through the ¼ mile while producing 600-650 RWHP typically. 

This is where we step things up with fuel system modifications for E60 blends and more boost. These are the most commonly used parts currently.

   In order to provide the most potential and run full E85 we recommend 

-Autotech HPFP Internal Upgrade +|

 XDI 21% Fuel Cam & Lobe (full E85)  Can get the XDI cam Here

We do not recommend combining the ZZP fuel lobe cam and Autotech HPFP internals at this time.
 

STAGE 3

If you’re looking to push the envelope even further with your ATS-V or CTS V-Sport we recommend further discussing your larger goals with us so that we can explore any & all potential options, as well as the risks & benefits. The LF3/4 aftermarket is growing at a progressive rate as we eagerly push this amazing platform. We love challenges & continually conquering new benchmarks with our team. 

Stage 3 Update: Turbobays gen 2 upgraded OEM LF4 turbos are providing promising data early on, seeing boost as high as 31 PSI with room to go and holding this boost curve way out into the RPM range 6500+ RPM where the stock turbos tend to struggle quite a bit.
