1999-2004 SVT Lightning-Harley F-150 SCT X4 Flash Device
JDM Engineering has been leading the way in Ford Lightning performance since 1998! After doing thousands of tunes on Lightning and Harley Davidson pickup trucks since their inception, there is no other Lightning tuner that can hold a candle to JDM for quality of reliability, drivability, and performance. We have tuned countless combinations of parts on these trucks!
Sub 10 second Lightnings and Harleys are just another day of the week at JDM. We also have a complete engine building side of the shop, and can make your 5.4 bulletproof for whatever induction system or power adder you'd like to throw at it. Click here to explore our lightning engine section.
Please allow 10-15 business days for your tuner to be shipped and is subject to change due to high demand.
