been running it the last 200 miles. No BS,m truck feels faster through first 3 gears. Actually has some "pick up to it" starts smoother as well, seems all cylinders light off at same time now rather than a 1 second roughness. Oddlyenoiugh, my tach sensor whcih worked for maybe 20 seconds a week, no works flawlessly everytime i turn the truck on. Maybe there was some sludge over the sensor? Dunno but keep oit up!
i got a 400 miles trip coming up with it, and by that time i should have approx 1500 miles on the auto rx, and my oil is due to be changed, so ill dump it and check out whats up in the filter!
