Review on 🚀 Unleash Your Vehicle's True Potential with the 3571 Superchips Flashcal by Brad King

If you are reading this you are either having doubts about your purchase or are looking for confirmation that this is correct. There are. I have 2012 4dr Unlimited Rubicon. I have 35" tires and lots of suspension upgrades. The 3.6's performance was okay, but I felt the shift points were far away, as was the speedo. I installed a cool Mopar Performance air intake that helped with throttle response, but my JK always seemed to be looking for the right gear. I have serviced a WA 580 automatic transmission for 30,000 miles with full synthetic ATF +4; better but not a complete cure. After doing a lot of research and reading reviews, I decided to give FlashCal a try. It took me a total of 20 minutes to reset my tire size calibration after a simple desktop update. The result was nothing short of amazing. My JK no longer felt like it didn't know which gear to put in place and shifting was smooth. I also took advantage of some simple functions such as B. switching off the chime with the door lock. Gasoline mileage increased from 12.3 to 14.7; it might even get better if I stop accelerating. I liked FlashCal so much that I decided to $$ upgrade to FlashPak; lovely. With a 91 octane performance tune, my JK runs like I changed the camshaft. I have a lot of smooth power from idle to full throttle; love the freeway now Conclusion on some of the negative reviews: If you have a Mac, you should install Parallels and Windows 10. It's not cheap (Parallels is $70 and Windows 10 is $119), but it works for me; My daughter uses Windows and Mac at school. Read and follow the instructions. Before first use, connect to the ignition and update the tuner. If you later want to upgrade to FlashPak; no problem. Follow the on-screen instructions when connecting to the OBD-II port; simple enough but be patient (and know the difference between ACC and Ign On but the engine won't run). The thing is almost reliable. Many reviews say it's overpriced and "one time use"; I do not agree. It's a lot cheaper than replacing a camera when you need more power. You can take this tuner off-road and control features like neutral and front/rear diff-lock for us Rubicon owners. And for those of us in a state of smog (like in California) I can put it back in stock for my two-year smog test and then quickly return to performance. I will definitely use it every two years. You will not regret the purchase.
