I believe the highest setting on mine is called "superchips".

I don't know what you mean by "below stock" setting? Mine doesn't have anything below stock. There's a "crawl" tune that's supposed to really slow down your throttle response, but that's separate of the throttle response options menu.

 

Yeah. I want to adjust it back to stock or even less sensitive than stock

If I recall there was moderate, stock, and super chips. I think I mistakenly chose the middle grade option so I am going to try reprogramming and making sure I select stock

 

Doing the initial set up at the computer, and then the really long and worrisome first introduction to the Jeep had me a little cautious. The website didn't quite match the instructions in the box, so that was a little confusing for a while. Then I figured I'd go conservative at first, so I only adjusted the tire size and did the 87 'quick tune'. That's why I didn't see the options for throttle sensitivity. Several others have noted how long it takes for the first time vehicle programing. That was about twenty minutes and during one of the file transfers, the check engine light aural chime rang continuously (for what seemed like ten minutes). That was pretty disconcerting, and I was fully expecting to have to tow the rig to Jeep for a factory re-flash. Well the good news was that it finally gave me the 'thumbs up' message that the tune was installed. By now it's nearly 2AM but I was really curious to see how well the speedo calibration worked, so I went for a spin. Speedo was close, but I tweaked it by .25 inches several times till I got it spot on with my iPhone's GPS. It was during those runs that I found I could not maintain a constant speed with my foot, and had to resort to the cruise control for a smooth speed run. Full disclosure here - I installed a Sprint Booster last week and was really liking the way the gas pedal felt after that super simple mod. But not realizing I had the Superchips throttle setting activation I was having a miserable time trying to maintain any slow speed operations. So I reverted the Sprint Booster to bypass mode and tried just the tune, still way too sensitive for a manual trans. (I'll bet it wakes up an auto nicely though).
Back to the forums.... I decided to investigate the other Flashpaq options and that's where I discovered that you can set additional option in the "Tune Vehicle" menu than you get with the "Additional Features" menu, and sure enough Throttle sensitivity is hiding there. So I'm to restore Stock Throttle setting - even the Moderate setting was just too much for my rig. Then I put the Sprint Booster back in the loop on "Green", and all is good.
I'm very happy now, throttle response is just right. I topped up with 92 octane fuel and installed the 91 tune. Oh yeah things woke up, and swear I can use 5th gear more now.

 

Everyone who has a superchip tuner in their Jeep should try the "Crawl" tune for the trails. It really slows the throttle response which is awesome for tight trails and rock crawling.
