whilst reading a thread on cold air intake i decided to have alook about to see what was available for my small engined car. its sluggish as it is but once the engine heats up it gets worse! whilst looking around i found the ets supercharger, it claims of more bhp (up to 20), instant boost, more torque etc. now is this just another "gimic" like the chips on the site that shal not be named costing a few pound and just containing a resistor in them or does this ets supercharger actually work? http://www.electronicturbosystems.com/ anyone had any experiance using them?
