[LostinTransit]

I'll not going to debate this. It is what it is and we're very happy with the results we've been getting so far. it worked because something simple was changed or this is a fluke. Seemingly after 3 years of driving a brick and while the slats did not open as much as I would have hoped, the engine was showing signs over heating.. Plus the transmission cooler (which is located above the radiator) wasn't seeing any air flow... After making this small adjustment, I can say the engine is running smoother, more robust and we're seeing an increase in the fuel economy. Plus we should see even more once on the open highway for a longer period of time. One more thing.. It also obvious that when the Focus ST and RS guys remove their slats to install inter coolers, they end up tuning their cars to get better fuel economy. We having tuned anything everything is still stock. This will be the last time I'll say anything about this. Debate amongst yourselves.
