One of the weak links in the ATS-V is the stock fuel system. Although adequate for OEM boost levels, once you crank that boost up many ATS-Vs end up having fuel systems that can’t keep up with demand. In some cases, the HPFP ends up sucking the LPFP dry thus entering the danger zone.
Paul from Florida has a 2016 ATS-V A8 with intake, BOVs, spark plugs and exhaust and 32,000 miles on the clock. With his previous aftermarket tune he was running dangerously lean which he discovered while on a dyno. Once he learned that he immediately switched to Tapout. The new Tapout Tune is much safer and he likes it better than the tune he ran before. However, now that his air/fuel ratio has been corrected we can see how the stock fuel system is not able to keep up with demand. Check out the blue and yellow traces in the scan below.
With this newly found information Paul decided to install a Tapout LP fuel pump. The following scan was taken one day after the above scan, with no other hardware or tune changes. It’s very clear how much more stable, safe and reliable his fuel system is now. Notice how both the low- and high-pressure sides have improved just from replacing the LP pump alone.
The Tapout LP fuel pump is an excellent product that solves an annoying problem on this platform. It is affordable, relatively simple to install and can show immediate fuel system volume capabilities on tuned ATS-Vs. Every day we are looking for ways to make the ATS-V better, and we’re proud to offer proven products like this.
