Selling my JB4 because I am getting a SonicTuned EcuTek tune. This thing is fantastic for extra power without risking warranty. I will remove the JB4 from my account as soon as it's sold. It also has the posi-taps for fuel wires and the billet aluminum enclosure.

Also please don't be discouraged by my lack of post history here, I have a Q50 so I'm extremely active on my infinitiq50.org account (1300+ posts) and have bought and sold plenty over there.

I can meet up in Tuscaloosa, AL or Birmingham, AL. I can also ship for an extra cost. I will only sell with PayPal Goods & Services or Venmo Goods & Services.
