i'm selling my hallman boost controller with the ceramic ball, and heavy spring only(pro rx). i used it for tuning the car, and then removed it. i ordered the add-on cable thinking i was going to use it, but i went another route. its all pretty much brand new, the cable is still in the box. asking $150 shipped and paypalled. the controller sells for around $115, and the add on cable goes for about $75, so my loss is your gain.
