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
500-550 RWHP give or take depending on the dyno. Similar mods on a Vsport can yield 450-500whp and run anywhere from high 11s to mid 12s range.
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, tune, would highly reccomend grabbing and AEM OBD2 wideband, and its a good idea to add a P3 gauge to monitor E content. We have seen as much as 550-590 RWHP from ATSVs on E30 tunes.

(optional but highly reccomended to keep an eye on E content easily)
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 E85 and more boost. These are the most commonly used parts currently. With the XDI HPFP and aux pump lowside added, E60-E65 Range is no problem. If wanting to run full E85, I would reccomend adding the 21% fuel lobe cam or mace cams as well
Similar mods on a CTS Vsport can potentially make 500+ whp and down into the basement 11s, with ATSV turbo upgrades we have had Vsports go as quick as mid 10s in the 1/4 mile
We reccomend LF3 and LF4 powered cars running ethanol blends and higher boost levels to run our 5w50 Supercar M1 oil and filter package which can be purchased here
Mods:
6. ATI Damper, Optional, but very good idea for engine health and longevity Click Here
If you are looking to go beyond stock turbo power, with upgraded turbos, there are additional mods to add to the mix such as:
With the auxiliary fuel pump you can skip the XDI LPFP upgrade and just run this with the stock LPFP as well.
Stage 3 - 700+RWHP
At this point you would likely want to have most everything listed above in terms of fueling and supporting mods to support upgraded turbos and potentially pushing the car up over 700RWHP
The "other guys" like to make a lot of empty claims on what works and what doesnt, however we have tuned ATSVs with the upgraded turbos we sell with full builds that have made as much as 775 RWHP, which is more than any ATSV has made with their turbos.
Fuel mods-
Supporting mods
-Mace Camshafts - Here
-Mace Valve springs- Here
-ATI Damper- Click Here
-APR Aged 625+ Head Studs- Here
-Turbo Blankets- Would also reccomend grabbing a set of turbo blankets at this time as they will help keep the heat where we want it, in the turbos for quicker spool times and increased efficiency Here
We currently offer a few stock frame turbo upgrade options
-TurbosRus (Here)
-Turbobay V4 (Here)
We have currently tested both of the turbocharger options above with supporting mods and mace camshafts, we have achieved 776RWHP/766 TQ with the TurboBay V4 and over 800RWHP with the TurbosRus so both turbo options are very capable and produce similar power levels, the TurbosRus produced about 16 more HP in testing while the Turbobay V4 produced about 15 more ft lbs of torque. As with everything, give and take, the TurbosRus seem to give a little down in the mid range in exchange for a bit more on the top end and vice versa with the Turbobay V4
You would want to get some larger inlets when running upgraded turbos, we sell ported and polished ZZP inlets that have been modified for larger turbos Here
Would also reccomend grabbing a set of turbo blankets at this time as they will help keep the heat where we want it, in the turbos for quicker spool times and increased efficiency Here
Supercar 5W50 oil Here
Brisk RR12s Plugs at 018 Here
We do not recommend combining the ZZP fuel lobe cam with HPFP upgrade
