RaceChip XLR Intial review.

    I received the RaceChip XLR with app control a few weeks ago and finally got a chance to use it. This is not to be confused with the RaceChip piggyback tuner chip, the XLR only changes the throttle response of the car.

    First thing I noticed was the inclusion of the serial number on the instructions first page for ease of use for app control. However, the instructions themselves are generic and not specific to the Stinger. It shows pictures of a hanging and floor-mounted throttle pedal as side-by-side pictures labeled A and B. This is not a problem as the install is quite simple and should take about 5 to 10 minutes. You will only need a 10mm socket to remove the hex bolt and nut in the picture below. 20180501_171802_resized.jpg

    After the removal, disconnect the throttle cable and connect the RaceChip.

    After putting the pedal back in place, attach the RaceChip to the car. I used the included zipper tape to attach to the underside of my dash.

    After adding the XLR to the app: Screenshot_20180427-082139.png
    I have currently only tried the sport(S), sport+(S+) and race(R) modes while in comfort mode. These settings gave me the results I was looking for by changing the throttle response while in the comfort mode setting and allowing me to keep it there after restarting the car. The sport mode on the XLR was on par with throttle response of the built-in sports mode; however, turning it to race mode felt as though it eliminated turbo lag entirely and made the car more aggressive. I plan on trying more settings soon when my work schedule permits.

    Thanks for the write up and review.

    Please tell us you re-gapped your plugs.

    I'm not sure the XLR requires any changes to the plugs. It's not tuning the vehicle, simply changing the throttle response. I know someone who has been using the XLR in his Stinger as well without any plug changes, no issues.

    Thank you very much for the review!
    The XLR does not add boost or power. No re-gapping or replacing of spark plugs necessary.
    By the way, it also works for the 2.0L engine, because the throttle system is the same.
