    F5 Flashpaq for Jeep® is rated 4.4 out of 5 by 88.
    Rated 5 out of 5 by from Wow I waited anxiously for 9 days for this baby to arrive. As soon as the UPS dropped it off I updated it and plugged it in. My 2007 JK no longer feels like a minivan. Throttle response is greatly improved, definitely feel more power. My speedometer finally reads correctly as well. I have only tried the 93 octane tune so far and havent put enough miles on it to check the MPG, but so far so good. My JK sat for over two years when I spun a rod bearing and didn't have the funds to replace the motor at the time. I got it back on the road about 2 months ago and until yesterday it was really underpowered. Thanks Superchips! Eventually I think I will be upgrading to the Traildash.

    Rated 4 out of 5 by from Great Company to buy from I had some problems with the ecm on my jeep after adding a supercharger. I expressed my concerns in a less than favorable review. To my surprise I was contacted by superchips management concerned about my problems. They not only listened to my concerns, they took the time to personally speak with the guys who finally tuned my jeep at Moab before Easter. This tells me powerteq goes above and beyond to support their customers and their product. They just flat out get it done. Thanks Superchips

    Rated 1 out of 5 by from does NOT work with CA emissions requirements Flashpaq is dead for any Jeep JK in California. California requires an update to the PCM for emissions purposes and it is incompatible with the latest Flashpaq software. California will hold registration without it, so there is no choice but to accept it. After that update is installed, the Flashpaq fails to recognize the vehicle and will no longer allow. I called support and they are unwilling to update their software, so beware if you are required to have a PCM update in California or if Jeep makes this update standard -- you will be able to set your tire size and not much else. Your $400 investment is gone.

    Rated 5 out of 5 by from Wakes it up I got this because the 3.8 is so anemic and I really realized it when we got my wife a 2015 with the 3.6. I did not want to do an exhaust or a CAI and decided to give this a try. So I did a quick test of a street start from 1500 to 5000 rpm and the 87 tune was almost half a second faster than stock. I am now running the 93 tune and I can feel that it is faster above 3000 rpm when I am passing someone. It seems to take about a week of driving for the Jeep to "get used" to the tune. Overall I am happy with the purchase. It's not like dropping a Hemi but 10+% increase for the price is not a bad tradoff. Haven't needed the tire size switch yet but it will be coming soon with the next set.

    Rated 5 out of 5 by from Pays for itself! I've had this product for two years now and couldn't be happier. Eco mode for my work commute saves me 3 miles a gallon! When I 4wheel I just swap to the 91 tune and have all the power back and more! I recommend superchips to all of my friends. Flashpaq for Jeep cannot be beat!

    Rated 5 out of 5 by from Awesome! I bought this right before I bought new wheels and larger tires for my 08 Jeep JK. Corrected my speedo and also gained my gas mileage back due to larger/heavier tires. Lots of features and tweaks! If your a techy guy or need one of these! Lol

    Rated 4 out of 5 by from Big Difference I installed a throttle body spacer and cold air intake but only got a slight improvement in throttle response and some noise. It wasn’t until I uploaded the 91 octane program from flashpaq that I saw significant results. My only complaint is that it didn’t offer much other than the 91 octane setting. I was hoping it would also have the 98 octane setting and the extreme setting available (I think that’s what it was called) but it was worth the investment. My 2000 Jeep is faster than when I first purchased it.

    Rated 5 out of 5 by from Great For Towing I bought this a few weeks ago after for my 2012 Jeep Wrangler in hopes of improving towing of my 17' travel trailer and improving shift performance. I've only tried the regular performance setting and 93 octane towing settings so far and I've noticed the biggest difference while towing - I have way more towing power! The regular performance setting has also improved the throttle responsive and brought back the power as I'm now running 33" tires. I love the option of being able to scan for codes especially when travelling and I'm unable to stop for a scan at the dealer. A lot of the other features are already available for changing through my Jeep but there are a few other neat features which I haven't yet felt the need to adjust.

    If I put this on a 2000 jeep xj with a cai and banks headers will it be able to account for that and boost performance more and what can I expect for mpgs?

    Asked by: Bill
    Yes, the Flashpaq tuning should compliment those minor modifications quite well. In a stock application, that 4.0L will gain around 24hp at peak, could be slightly more in your specific vehicle. As for mileage, that's always subjective depending on many variables, but our calibrations are optimized for better efficiency over stock files.

    Is there a non jammer cold air intake tune or setting like the diablosport tuner?

    Asked by: 5 tires
    If you're running another quality brand intake system, the Jammer tune should still work great for your needs.
