Did a little further testing yesterday. There is a noticeable improvement, albeit small, by cracking the stop open approx. 3/4 turn. Gather it took a little time for the PCM to relearn the new airflow. Gains are most noticeable between 2500 & 4500 RPM's, with better throttle response and pulling power. Fuel mileage was unaffected, possibly better. Got 33.2 mpg (Imperial) 27.7 (USG) combined highway/city on a 300 mile trip. For power comparison purposes this gain is about half what I got from the SVT t-body upgrade.
