I've got about 300 miles on it so far and no issues. The fuel economy is slightly better, but the jury is still out on seeing if it runs smoother with small throttle openings. Sometimes it is smooth as silk and other times it wants to buck. I want to get out and re-connect the O2 sensors and see if that makes a difference.
Is yours box stock, with O2 sensors connected and secondary butterflies still installed?
