F5 Flashpaq for Jeep® is rated 4.6 out of 5 by 70.
Rated 5 out of 5 by from GOOD SUPPORT i bought the flashpaq 3874 and installed on my 2008 jeep jk, after installing the tune for mileage save; the pcm stopped working, i contacted superchips support team and someone called Rich McKenzie contacted me from powertech. he tried to save my pcm many times sending me ignition updates but it didnt work, he asked me to ship the ecu to powertech and they will reimbourse the shipping fees, but the shipping was too high and then he sent me a new programmed ECU, whenever i just plugged the ecu, it worked, the ecu was free of charge. in conclusion, superchips support is a responsible department that covers damage, i recommend this item for everyone

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 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 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 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 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 Must buy for lifted modified Jeeps I love this product. It leveled out my throttle response, helped a little with MPG, and has given me more HP. It also corrected my Speedo that was about 8-9 MPH off at freeway speeds. Great Product.

I'm looking at a 2007 Jeep Cherokee 4x4 with the in-line 6 cylinder engine. Will this tuner work? I would be purchasing it primarily for fuel savings, so what kind of Hwy mileage could I expect in Economy Mode? Duramax/Flashpaq owner & love it!.

Does the Flashpaq or Flashcal have the ability to turn off the ESP mode for an 07 Wrangler?

Asked by: TroutBum
It will not disable the esp but our device will optimize it. If you are looking to disable that i would suggest checking out our Sister company Diablosport

Asked by: Hunter6654
