I am selling my older JB2 with the X upgrade. The X upgrade has an adjustable boost knob to adjust between 13-15 psi as well as a race gas switch (formerly known as the R switch). It's a very powerful tune with only about 6 or 7 wires. I have the install instructions printed in color. This is a great tune for a more than modest power increase (more than JB+) for a cheap price. I started asking $50, but I'll send it to anyone for $35 or best offer.  Last edited by Blue Streak; 02-01-2011 at 06:45 PM.. |
