Pairing tuning that is designed to account for increased airflow, from a high efficiency intake, is the best way to build power on late model gas vehicles. Reaper Stage 1 Kits take the guesswork out of trying to pair performance products from multiple companies by adding all the components in one high performance package. Now you can take your ride to the next level with the Reaper Stage 1 Kit from DiabloSport. NOTE: ON 2019 MODEL YEAR VEHICLES, YOU MUST SAVE YOUR STOCK CALIBRATION WITH YOUR TUNING DEVICE BEFORE REMOVING THE STOCK PCM FROM THE VEHICLE.
