To match PVT's polished FRPP CJ 123mm mass air housing, we opted for the polished version of the VMP dual 72mm throttle body. It is a beauty, and at this point, an easy bolt-on. Now you can run VMP's smaller dual 67mm unit with a stock elbow, but the high-flow inlet elbow is required for the dual 72mm unit. Of course, adding such a big throttle body requires some tuning. "When a larger-than-stock throttle body is installed on any electronic throttle control vehicle, the drive-by-wire tables should be recalibrated," Justin explained. "Proper recalibration of the tables is necessary to prevent the dreaded wrench light or failsafe mode."
