Actually it's normally the off the shelf systems that give you little gain. If say you were having a turbo/supercharger/THB's fitted, youd be better off going to Powerflow as they can taylor a system to your car much better.ticki wrote:fairy fluff mate. But Powerflow will give you little or no power gains.
But bare in mind some Powerflow depos are excellent, some arnt so good.
An aftermarket one is only good for a car that has minor engine mods such as cams and remapping, as it has been designed for a standard engine only.
