F5 Jeep Flashpaq is rated 4.7 out of 5 by 55.
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 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 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 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 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 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.

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 4 out of 5 by from Good Product Just got this yesterday. Done an update online before using as I have read that you really need to do that first. Plugged it in and picked the mods that I wanted or needed. First I changed the tire size to the oversize tires on my jeep by measuring from the ground to the top of the tire and that set the speedometer and odometer, it is now dead on the money. This improved shifting on the automatic transmission considerable also. Next after making sure I had a full tank of 93 octane fuel in the tank I set it to the 93 octane performance setting. Went on a 400+ mile trip today that consisted of highway and dirt roads as well as some idle speed driving on a wildlife refuge. The engine is no longer sluggish and I don't have to press the gas peddle near as much to make it up hills on the highway and my gas millage has Improved about 4 to 5 mpg. It ran smooth and peppy with no overheating or pinging. Got on it pretty hard one time on a sandy dirt road and I'm happy to say that I am quite pleased with the product. The only thing I wish it would do is let you choose the air pressure on the TPMS instead of just on or off. Haven't tried the crawl setting yet but will when the going gets rough. Haven't tried the fuel save with 87 octane either but am getting better millage anyway with better performance. That's about it for now. I'm happy so far.

I see above that this will not do tire size adjustments on my 2003 Grand Cherokee 4.7. Do you have an alternative? Tire size is of utmost importance to me. Thanks.

Asked by: ThunderChief
There's some kind of line drawn at the 2003's and up Grandplan. I guess they work on 03 and up but not 99-02. Maybe Anthony can explain it better for us please?
