Product Description

Bought an SCT device from another company and not happy with the results?


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


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 20,000 vehicles (yes, you read that correctly).  We operate out of a real building and are not your typical fly-by night internet "car tooner".

We offer custom tunes for multiple modifications that other companies do not such as non factory supercharged, turbocharged applications and nitrous oxide systems.


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.

    Posted by for CHASE Riley on 1st May 2017

    We got the 3 tune custom pack for my son's blown 98 Cobra.
    Wow, right off the bat.... car starts better, idles better, and runs like a raped ape! :-) Very happy, and can't wait to try the race tune at the track. Thanks guys for the quick personalized service, and answering questions with this custom application. Many companies can do mail order tunes, but JMS knows what they are doing and gets it right...quickly and accurately. Very Happy.
