I was frustrated with bad MPG and lack of power with my 3.8............
I tried a JET performance chip and a cheap air intake system....Didnt help at all.
so i saved some cash and did some research.
And got an AFE stage 1 cold air intake and the Superchip 3875 tuned to 91 octane performance..
and i was blown away by the change, its like a whole new engine, HUGE gains,,in performance and MPG...
I strongly recommened this...and ive owned 6 Jeeps and researched many products.........GET it

This tuner works! I live on a hill and now I don't have to use the overdrive button in the middle console just to maintain speed going up the hill. The vehicle shifts when it is suppose to now. It fixed the transmission programming and throttle response. The shipping of this product was fast and packaging was sufficient.

Bought this for my 02 WJ 4.0L on 32's. Put a cold air intake on, 62MM throttle body, cat delete. Motor was idling odd so I thought I'd try this product. Kind of expensive but ended up getting 22MPG highway! On 32" MTs. And noticed more power

Vehicle: 2009 Jeep Wrangler Unlimited Rubicon, Manual Transmission, 37" tires, 5.13 gears, 4.5" Rubicon Express Long Arm Lift

Purchased the Superchips 3875 Flashpaq for a 2009 Jeep Wrangler Unlimited Rubicon that I had purchased used. The prior owner had a 4.5" Long Arm Lift, 37" tires and 5.13 gears without making any computer changes. On my drive home, roughly 80 miles up and down hills(Colorado), I got roughly 11-12 mpg. This was at 65-70 the whole drive. I thought it may have been wrong so I filled up and got about the same again, around 12 mpg. Purchased this after reading reviews at a few different Jeep sites and on Amazon hoping it would give me at least 2-3 mpg better gas mileage. Setup took a little while as it HAS to be plugged in to get the updates from superchips but it was necessary so I had to be patient. Once I finally was able to plug it into my Jeep the initial process it goes through to record the stock tune didnt really take that long and I was on my way. I set the proper gearing, then set the tire size to the proper height so that the speedo was adjusted properly and decided that using the quick tune 87 Octane tune would be better than the mileage tune for getting up the climbs and passes. Initially, after taking it for a test drive I was just happy that the speedometer was showing the correct speed. I filled up the Jeep and drove it to work everyday for the week and was pleasantly surprised by the jump in mileage. My tank lasted me a little over 340 miles and after fueling up a smidge over 19.5 gallons, I figured my mpg which was right around 17.5 mpg. I had gained roughly 5 mpg and the only change was the Flashpaq. NOTE: Before using the Flashpaq, in 6th gear at roughly 70mph, the Jeep was running at around 3000 rpm's, after using the Flashpaq, at 70mph, the Jeep is running at 2600-2700rpm's and I am able to pull the mountain pass in 4th and 5th gear instead of 3rd or 4th.

If I could give this 6 stars I would. I was skeptical at what kind of a difference this could make - but it does! My JK is no longer sluggish and the shifting is smoother. Gas milage has also improved. I use it on regular octane set up, but also tried 93 octane set up - didn't need that much extra pickup - but I'll use that when loaded down. Great product and worth every $.

I bought this product to help give my 08 JK it's pep back after installing a lift kit and 33" tires. I was getting around 15mpg before install after I am getting between 17-18mpg. Also helped the shift points with the transmission considerably! I have been running the 91 octane tune.

Since I bought my Wrangler a year ago, I have liked everything except the pinging under a load, and the transmission going to high gear way before I wanted, so I had to resort to keeping overdrive turned off and even using the select shift to hold it back in 2nd until I was well ready for it to jump through 3rd and on to 4th. It drove me nuts. I started reading all of the excited reviews on the SuperChips Flashpaq and finally forked over the money to buy one. When it came in, I plugged it into my port under the dash, it saved my stock programming in the unit, then asked me a series of questions to know how I wanted it programmed. It downloaded the new program into my onboard computer and PRESTO! Holy Moly! It has never ran so smooth on the highway, does not ping on 87 octane (partly because the power band is properly tuned) AND it shifts like a new transmission! I would not have believed it if I hadn’t done it on my own rig. My wife is now getting tired of me bursting out on the highway with I LOVE MY JEEP. LOL

I only wanted something to adjust tire sizes on my jeep. this does a little more, paid a little more but worth it. I really do wish i had spent another 50 bucks and gone another step for one that mounts and is always plugged in and does a few of the fuel economy things .... i suggest you move up a step w this. BTW the tech support is great, unfortunately i have had to use them a couple times to reprogram updates which is really why im giving four stars.
