ordered the rokk tech adhustable sensor this AM

what should I realistically expect from this item

truck is getting 17-18 mpg anyway at 10k or so on the odo

not looking for performance so much, but as we all are, looking for mpg increase

 

I picked up about 1mpg, but I also only got 3/4 of a tank through before I had to fill up on winter diesel (yuk!) so the gains may be more. So far on winter diesel I am getting the same as I did before the ROKK sensor install on #2 diesel. I also noticed an impressive change in the low to mid powerband. It is like a different truck...in a good way! I always had a bit of a shudder/stumble starting off in 1st and 2nd gears (engine related) with the ROKK sensor take offs are now smooth as can be!
My opnion is, it is all good and worth every penny, unless one wanted to try the free tone ring mod instead as it is just as good.

 

COULD SOMEONE EXPLAIN WHAT THIS IS AND WHERE TO GET IT [rokk tech adhustable sensor ] AS I HAVE NEVER HEARD OF THIS BEFORE .
