Superchips Flashpaq for JK, Initial Impressions


Might give that a try, it worked for me....
Just got mine in yesterday (thanks Northridge!!) updated and installed it last night.
Settings I used where for the 87 Octane and adjusted tire size to 33.75, which is roughly what mine are.
Not really noticing any difference? I do a lot of highway driving (roughly 120 miles a day; for now) but even in the city I still didn't notice a change. Mileage has stayed roughly the same, and I am still having issues even trying to maintain a steady 70mph (speed limit here) on the flat highways of the coast. Maybe I was expecting too much, or maybe it didn't program properly?
Any thoughts?

I bought mine a couple of days ago and loaded the 87 tune. (My windshield wipers and lights were on during the process too). I can tell a pretty big difference in seat of the pants. It pulls a lot harder and suprisingly it feels like it's got a bit more torque too. The shifting is definitly improved (Automatic). I do my mileage on paper every time and I haven't run a full tank yet but my dash indicator used to stay around 19-20 MPG and now it's hanging around 22 MPG (I reset it when did the programming). I drive 90 miles a day on the interstate so no idea on mileage in town / traffic yet. Overall it has exceeded my expectations. I may run a couple of tanks like this next week and then switch to the milage tune and see if there's any change.
Harder / Firmer. Mine used to feel like it slipped too much, especially between 3-4th gear. It now feels like I think it should. It's hard to say powerwise what the increase was but it pulls a lot harder when merging on the interstate and pulling into traffic. As I said, I was surprised that it feels like it has more power without winding the engine up.
