luckily I have no "psss" sound from my pop charger. If you have ever had an AEM CAI the sound is similar.
BTW, I killed an integra and Civic tonight. They pulled up in the two lanes left of me. I though I eould joinn in and so when the light hit green the three of us went at it. What a joke. I smoked them!!!!
Also, after installing my pop charger my Idle has smoothed greatly. The steering wheel vibration I reported has diminished greatly :?:
