Rated 5 out of 5 by billrossi85 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 2013 Dozer 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 bulkfryer 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 Terpsmandan 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 Kyfarnes 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 Ozone1965 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 4 out of 5 by JKSam 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 rova4evrr from It's Crazy I bought a Flashcal for changing my speedo for 35" tires and being able to shut off the TPMS sensors for tire pressure at 8lbs. at the Dunes years ago. Just today after a few years I upgraded my Flashcal to a Flashpaq. I changed the tune to 91 octane (even though I'm running 89). Then I changed the Pedal response just to Moderate for a Lets See. Just off that change there is no more lag in the pedal. It's CRAZY an just off that it's got more get n go. I'll run it like this for awhile then change it an try another setting. Also Customer Service is Fastastic *****. Needed help with the upgrade and Conrad Is The Man!!! Thank you, Bob South Bend, IN '12 Jeep JKU

My local gas octane levels are 87, 89 &93. Can I use the 91 performance tune with 89 octane?

Asked by: Warrent86

It could be, but you'll need to pay close attention to make sure you don't experience fuel knock. You'll get your best performance gains with higher octanes.

Our Flashpaq will allow speedo adjustment for larger tires on your Grand Cherokee. As for power gains, in the 4.7L we've seen as much as 21hp/20tq at peak with improved throttle response and better drivability.

I have two jeeps. can this unit be used for both? I know they will both jk and wk2. I just want to know if this unit has to be plugged in 24/7. or can it be disconnected. Does it have to be plugged in to work or can you set your options then unplug? 

Asked by: Dani123

The device does not have to be plugged in all the time, you can use it to adjust your options and flash your tune then remove it. However, if the device is used to change any functions on the vehicle, it will be vin locked to that vehicle. They will only work on one VIN at a time, so if you have two Jeeps, you'll need one for each .

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.
