Vengeance Racing has five levels of performance packages available ranging from mild to extreme to meet your power goals while retaining GM’s LT5 supercharger for the 2019 Corvette ZR1. Our performance packages start with a simple bolt-on package retaining the stock engine combination and focusing performance increases with better airflow and higher boost levels. This bolt-on packages allow for like-stock drivability keeping the car mild mannered on the street, but a monster on the track! If you’re still looking for more performance, our Stage 2 and 3 packages let our technicians dive into the valvetrain of your engine to further increase air flow and efficiency of your engine, and provide that signature sound that everyone loves from an aftermarket camshaft. The Stage 3 package offers the most performance output possible with the use of methanol injection and E85 fuel to allow us to safely run much higher boost levels. Flex fuel capability is currently not available, but Stage 3 does include our EFI Live AutoCal device to allow you to switch between 93 octane and E85 tunes, as well as data log the vehicle while on track!
