What upgrades can be performed from the stock Porsche CIS systems? What kind of HP gains can be made and at what cost? .... or is the CIS a pretty robust system and should be left alone?
Perhaps there is some confusion here. The CIS mods only support power enhancing upgrades such as custom turbochargers, headers, intercooler, boost level etc. Upon or after installing these upgrades the CIS may need to be enhanced to prvide fuel flow if you develop an output beyond ~350HP. There is no improved performance (HP) derived from the CIS mods alone.
