Arrived on time and it was easy to install. Stage 1 with no modifications. Similar results to what others experienced with the same set up and power plant. Noticable difference in performance. Improved low end performance with less lag in throttle response. Better take off from complete stop. There is a definite improvement in the midrange power band when driving in heavy traffic. Approx 500 miles driven since instilation 70% in town. Fuel milage increased from 11.5 mpg city to 14.3 mpg city. Not enough milage driven on long trips to see it there will be an improvement over the previous 18 mpg on the highway. Purchased to improve fuel economy and towing. Would definitely recomend for similar vehicle set up.
