    F5 Flashpaq for Jeep® is rated 4.4 out of 5 by 89.
    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 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 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 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 Worth it, little frustrating but worth every penny I purchased this and had some issues out of the gate. My biggest gripe would be the process is not outlined very well between the on screen and manual directions. Customer support got the issue figured out and I'm up and running. I'm running the 85 octane millage program and have picked up 1.2 to 2 mpg's. pretty impressive considering I have a 20gal tank and a thirsty Hemi. I seem to have settled in at 14 mpg combined. Slightly better than what I would average with 89 octane. This has extended my millage enough to where I can go an extra day or two before visiting the gas station.

    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 4 out of 5 by from Good tuner, but had some issues after removing This will be a two part review: the first focusing on the tuner and the second on a major issue that I have with the product: Tuner: -Feature Rich -REALLY wakes up the JK -Easy to use (with one big caveat, see below) -Well built physical unit Issue: The Ignition software (which is integral to having the latest tune on your vehicle) is SEVERELY lacking. It's slow; it's clunky; it's not well done. The biggest issue I have is when it comes to uninstalling the tune from your vehicle. This process is poorly documented and there isn't a good test to ensure it is unlocked besides plugging it into another vehicle. I reverted the Jeep back to stock before it was sold and everything looked like it was fine and that my Superchips tuner would be unlocked for use with another JK. I give the tuner to my friend and the tuner was still VIN-locked to my JK that was sitting at the dealership already. \ I decided to just pay the $100 to unlock it, but the Ignition software is very poorly done. It wouldn't recognize the device on multiple machines or would error out when updating. Once I finally was able to get it updated, the only option that I was offered was to buy an extended warranty. I understand the reasoning for the VIN-lock, but the process for unlocking is not well defined or clearly done. Having the pay the $100 because of ambiguous unlocking guidelines/confirmations was annoying enough, but now I cannot even do that. That is frustrating and soured the experience.

    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 gal...you need one of these! Lol

    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?

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

    Have a Jeep 2011 used it to calibrate tire size to speedometer. Do I need to set back to factory settings before getting alignment done?

    Asked by: Ry82
    Just to be safe i would. If the Jeep is going to the dealer for the alignment they may have to flash the jeep with an update if they have any available so returning to stock would be the best option
