PSD truck loping meant to sound cool like...
MUSTANG loping due to the huge duration and overlap on the cam lobes, designed for higher rpm power.
i said it before, just my opinion but if you want the idle, build the engine to idle that way. i could pull the ccv hose off my mustang intake and it would sound cool like that, but whats the point?
also....the lope/smoke video i posted looks like those cylinders are being washed down bad from all that unburnt fuel.
