JMS-Single Tune

JMS can create 3 custom tunes specifically for your vehicle! After ordering your programs are sent via email.

Ford custom tuning -> (1988 - 2011) Every Ford vehicle supported

GM custom tuning -> (1998 - 2011) Supported engines 4.8L 5.3L 6.0L 6.2L 8.1L 6.6L LS7 LS9 LS2 LS3 LS6

All custom tunes are created based on our extensive experience on our THREE in-house chassis dyno's.

JMS custom tunes are the best possible tunes available for your vehicle period.

We are SCT's oldest and most trusted dealer with over 45 combined years of tuning experience. JMS has been in business since 1993 and we have tuned over 20000 vehicles (yes you read that correctly). We operate out of a real building and are not your typical fly-by night internet car tooner.

Please fill out the form with the requested information. If you have any questions please give us a call or send us and email.

Once your order is placed a JMS representative will contact you via telephone or email to discuss your custom tune(s). Or call 601-766-9424.

    Thanks a ton

    Super easy to work with and customer service was awesome. Installed a supercharger on my car and they sent over a tune faster than I was expecting. Car started no problem and I can’t wait to get in for some dyno tuning. Thanks again jms.
