Want to add more horsepower to your C8 ZR1 and don't know exactly how? Take the guesswork out of things and allow Peitz Performance to take your ZR1 to the next level with our dyno tested and proven Charlie package! We developed this package with overall driveability and durability in mind, not just peak horsepower and torque. The standard Charlie package includes a Halltech cold-air intake box, Peitz Performance catted downpipes (featuring 3.5" inlets to cats), tune, unlock, and credits. Options include an MS 109 tune and a Peitz Performance Remote Tuning Device or MPVI 4 if you really want to turn it up to 10! This also allows you to switch between race gas or 93/91 tunes. Contact us for installation quotes if you would like to have it professionally installed at our shop. See dyno graphs for additional horsepower and torque output details.

After purchasing the package, we will reach out to you and coordinate for you to send your ECM to HP Tuners for the unlock. We will need your VIN in order to process the order. You will receive your ECM back with an MPVI 4 or you will receive a Peitz Performance RTD separately. After getting your ECM unlocked, simply plug your HP Tuners device directly into the OBDII Port, connect to your phone or laptop (depending if you are using an MPVI 4 or RTD), 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.
