All i am saying is, i dont disagree that installing all these mods will/may increase your cars performance and efficiency. But if you don't have the time,understanding and a proper mechanic to fix the accompanied issues you will end up being more dissatisfied. People are still solving RPM issues on CNG, every third post on PW is about cars not maintaining RPMs.
Adding all this equipment to your daily runner does'nt make sense. For me, i drive around 25 Km daily to work and back during rush hours. Any mods id ever like would be the ones that can improve my mileage.
