    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.

    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

    What are the power increase numbers for the 2.0 tune? Do you have a tune for the 2.0 or just 3.6?

    Asked by: Ogjeep
    We are still working on the 2.0 tuning. We only offer tire/gear adjustment on the 2.0 at this time. Check back in a couple months

    I understand OEM's sometimes tune engines on the lean side to decrease emissions at the cost of decreased engine power and increased combustion temps. Does the Performance Tune (87 octane 17hp 18tq) increase fueling only and leave timing at stock values?

    Asked by: JonB
    We adjust fuel/timing on each of our tunes

    Is the Flashpaq F5 compatible with the 2.0 turbo in the JL? When I search the site only the flashcal comes up with this motor combo. Want to be sure before I order. Thanks

    Asked by: wjethro
    It is not at this time. The 3571-JL Flashcal will work on the 2.0

    Will dealership be able to tell I'm running an unlocked PCM? What's process to return to stock configuration when taking my vehicle to the dealership to ensure no loss of warranty? Will I pass California smog if I return to stock config before testing?

    Asked by: IMustBreakU
    We use factory Chrysler pcms. The dealer cannot tell

    Hello. I was wondering if can unlock the Cargo Cam on my JL 2018? I wish to purchase a Front camera for Bouldering. It would be awesome if this product can also enable the front camera on the software.
