I would like to seek some other opinion from the turbo otai about this subject. As we know NA car compression ration is about 12-14:1. Bear in mind that is negetive pressure, the most is 0 bar or atmospheric...
Planning install Apexi Power FC on my Altezza 6mt.
Is it worth buying? Since im stock n/a engine, with catback system only.
Will there any difference on the performance?
