Improve your CT5-V Blackwing's performance and drivability with a Peitz Performance Delta tuning package using HP Tuners software! We developed these tunes with the overall driving experience in mind. Not only will you gain power at wide-open throttle, but you will also feel the difference at part throttle via improved throttle response and much-improved shifts if you select the TCM tuning option! This tuning package is intended for mostly stock or "bolt-on" Blackwings including cat back exhaust and air filter/airbox modifications. If your car has additional modifications, please select the custom tuning option to get tuning even more so tailored to your vehicle
After getting your ECM unlocked, simply plug your HP Tuners device directly into the OBDII Port and connect the MPVI 3 to your laptop and read the stock file out, and send it to Peitz Performance. Peitz Performance will write the tune and send it to you and walk you through the process from there.
Programming the Stock ECM with our calibration will net you up to 20 HP with just a flash!
Select the E85 option if you are going to blend E85 into your fuel to gain some additional octane. We have only tested up to 30% blends currently with the stock fuel system and it definitely helps stave off detonation.
If you have already had your ECM unlocked and have an MPVI 3 device, select the appropriate options for just tuning support from Peitz Performance!
