This not my area of expertise, but did they tune it only at WOT or for idle and cruise and such as well? The computers also learn and performance should increase over time, a tank or gas at most I would think. See if it smooths out after a few hundred miles.


They did the dyno tune and then we went out and did a street tune as well. He kept an eye on the air fuel ratio and adjusted something 3 times while we where out driving around he probably drove it 20 miles in total highway-intown and backroads. I tried to pick his brain as we where driving but most of it was way over my head. He would point to a chart and say this number means this and I want to see this, But that chart had like 300 blocks sooo it was alot to take in.

I did the HP Tunes, DOD delete yesterday
Initially thought about buying a Range OBD ll adapter, but after doing some research on it, with all the battery drain, and other problems. I decided to find someone who could do a HP Tunes on it..
The AFM delete cost me $175, and took him about 15 minutes...
The Range OBD ll adapter would have cost me $199....
So I figured i got a better deal long term, and cost wise...
Haven't had it long enough to tell if it makes any difference fuel wise...
But the truck seems to be operating like it should...
I got it done at Tunes Inc, in Jacksonville, Fl.

My mpg has dropped from 13.8 to 13.3 since the tune but I havent gone through a tank yet, Also having a 4 mile round trip to work every day and I switch between that and my forester means it's going to be awhile before I go through a tank . Hopefully it will get better.
