FAQ
Do I need a bigger pump and turbo to run 300% over injectors?Yes. A 300% set demands substantially more air and fuel. Plan for an upgraded CP3/dual fuelers, a proper turbo system, sufficient lift-pump flow, and custom calibration. Running these on stock components can lead to smoke, high EGT, and poor drivability.
