I recently installed an HKS PFC F-CON on my car, and have noticed a strange occurrence. Every time i give it gas, and I hit full boost at 3000 RPM, my car jolts very roughly. I know the fuel cut is installed, and I am running:

Down Pipe, HF cat, Catback, street ported engine, HKS PFC F-CON.

Every time I am on the gas, whether WOT or just gently passing 3000 RPM, I feel the fuel cut. When at WOT, the car lurches really hard, and if I keep flooring the pedal, I will not be getting boost all the way through the first gear, or until I let go of the gas. When pressing the pedal gently, I feel a slightly jump forward, and only after that can I start building boost, and getting my turbos to get going.

Is this normal with a fuel cut, or is there something I should look at?

Thanks,

-Daniel

 

sounds like the secondary injectors aren't coming online or something
