I installed mine on Friday. Drove to Durango and back this weekend. I have not topped off the tank yet from the return drive, but I did not see any improved fuel economy after the first two tanks. I remain at 17.4 MPG for HWY driving and actually a little higher goofing off around town?
I'll let you know what the 3rd tank shows.
1. How long does it take the ECU to adjust to a new MAF sensor?
2. Could those of you who have seen an increase in economy have benefited just as much from cleaning your existing MAF sensor?
Over all I "think" the truck runs a little smoother at and just off idle, but as Chris pointed out it could just be a $300 "power of suggestion"
