I have never tried the Pantera system but I can tell you the Kinsler unit has a unit to install an idle air stepper motor on the idle circuit. There are many brands on the market that do not. But we have that circuit on the truck which is why it idled so good out of the box on the dyno. The guys at Westech commented on the idle quality when we ran it, they were not excited about tuning an IR engine, because of that very fact.
You can see the 8 stainless lines and the stepper motor and airfilter in the manifold. We since relocated the stepper motor down near the oil pan.
