    Rated 5 out of 5 by from Works PERFECT!!! Customer Support is AWESOME!!! I bought this about a year ago, and has worked fantastic! Only issue I had was when I re-geared my axles, I was having difficulty getting the settings to take. I contacted Customer Service, and they knew the exact procedure to reset the ECU, which solved the problem. Couldn't be happier with the product or the company.

    Rated 5 out of 5 by from 2.0 Turbo JLU Flashpaq is awesome I waited for this to be available for the 2.0 liter engine. Our engine runs smoother, stronger and better than ever. I am so happy I waited for this product. I love the other features to control sway bars, lockers, auto-run/stop etc. The PCM swap was fast and easy. I think they did a great job with this and the process. Would do it again.

    Rated 5 out of 5 by from Great Tune Easy to install, great tech support. I run 93 octane with the 91 tune. I also towed a 3,000 lb camper from Oklahoma to Florida on the tow tune and it performed great!

    After you finish the install and tune your jeep, do you need to keep the bypass module installed? Or can you remove it?

    How do I process an order for just the F5 software JL2.0 update and PCM swap if I already have the Flashpaq F5 from a previous Jeep JK and what to use it in the 2018 JL 2.0L turbo? NOTE: The F5 was returned to stock before trading the JK for the JL.

    Hi, does this also improve throttle response like pedal Commander?  I’m very interested in reducing the drive by wire lag and don’t want to buy two different products.

    Asked by: DadWagon
    This does not have any settings for the throttle response but we do offer a product that will. Check out our AMPD throttle booster
