I drove 1100 miles from Florida to have JDM sprinkle their magic dust on my 2014 Roush Raptor with 100k miles. The tune transformed the way it accelerates, shifts and overall feels like a different truck. They also changed my SC oil and belt which was needed. Overall, I TRUST JDM, Jim Sr and Jr for my truck’s needs, with their years of experience and excellent customer service!!!Thanks Again, Joe

This place is amazing for your mustang fixes. My car had problems beyond what I think a dealership would have been able to fix and Jim senior fixed them! He really knows his stuff and was able to fix every issue with my 2017 whipple supercharged gt350. This car has never ran this good before and there was a lot that needed to be reworked. I would highly recommend JDM Engineering to anybody who has problems with their modified cars or even stock cars. These guys are going to be my new mechanics for any uprgrades or problems I may have in the future. They are real stand up and meticulous guys. Thanks again Jim!

This place has the best cams for the 13-14 GT500, and the best motors for sale for those years, with a warranty.

This is not a bad review. I almost gave you 1 star but instead gave you 5 stars because I did not want to affect your business. Your name is very confusing. I almost drove 2 hours to your shop until I read in your description that you are specialists in Ford. In the car enthusiast community where you happen to be operating, JDM stands for Japanese Domestic Market which means Toyotas ,Subaru, Hondas , Nissans etc. Not Ford. I know you know this. maybe you could consider changing your company name or become specialists in true JDM cars

I’ve been with JDM since 2008 on (4) different vehicles: a 2001 Lightning (JDM built short block), 2005 Roushcharged F150, 2013 Whipple Supercharged Raptor and now a 2007 GT500. I can’t say every project was easy but each time these guys have stood by my side and helped me through to the end. This is customer service at its finest and a company that is proud of their products and services. Special shout out to Jim Jr and Nick I appreciate you both

Jim Jr. worked on our 2020 Shelby Super Snake that was having issues with too rich too lean codes as well as misfires. Solved the problem and the car runs flawlessly! Will be bringing car back to them for all work!

The best

Had a few issues with getting my card accepted by these guys and shipping contingencies. the staff at jdf are helpful and professional.

Our friend had some work done. These guys really know their stuff and are super friendly!!!

Great honest, loyal people in this business. Excellent custom work.High quality work. Theyre the best.

Very professional and extremely knowledgeable. What a great experience! Highly recommend!!!

Fantastic place to do business with. Jim and Nick took care of me Exceptionally well through the entire process of building my 5.4 F150 motor, blower, and other components. Couldnt ask for better service, period! I only wish I was closer so I could go there and meet them to thank them in person.

Great Team! Have used them since 2007 on various Ford vehicles always spot-on from a Ford Lightning to a Mustang to the EcoBoost have purchased many Tunes all are amazing! Have purchase complete Motors as well as various other parts through out the years even if you just need information they are there for you if you own a Ford these folks are the people to deal with!!

Jdm engineering but only work on fords 😆

I have owned a Saleen Dan Gurney Eagle Mustang for many many years, and the car has always given me fits...going into limp mode under hard acceleration from time to time. I finally had ENOUGH! And at the recommendation of my good friend Peter Miller, I contacted JDM and Jim Jr. He walked me through the entire process of having a custom tune made for the car. Told me that Saleen supercharged Mustangs are sorta notorious for this kind of “hiccup”. Well after a few phone calls, and long distance diagnosis (I’m in Phx.) Jim had a custom tune designed for my car, explaining that this should cure what ails it. Well, when it arrived at my home, I had NO idea what I was doing, so once again, Jim walked me through the download (or is it upload?) LOL process and low and behold the car is like a BRAND NEW CAR!!! I actually have no fear of getting stranded anymore and it’s actually fun to drive once again! I want to thank him for all of his ungodly patience with me, and echo what’s been said on Google here time and again..... Class operation, super helpful and polite and a fabulous outcome. I will always recommend JDM to everyone I know with a hot rod! Thanks a million Jim Jr.Chris Hall

Jim junior has been amazing with helping me get my parts put together and shipped! I recommend them to anyone I know looking to modify or build their vehicles 👍 awesome job guys

Very knowledgable and friendly..this place is in new jersey..my husband had his drag car there for some tuning

I can’t say enough about JDM team. I currently own a 2018 5.0ROUSH F150 and was in the market for a custom tune. As you all may know you can buy a “tune” online but nothing compares to have a custom tune by JDM.About a month ago and after doing my own research I walked into JDM and had the pleasure to meet Jim jr. Jim who is extremely knowledgeable and personable took his time explaining the tune and results I would see. Right then and there I knew found the best place to do what I wanted my truck to do.Yesterday I went down to JDM to have my custom tune installed and to put this into one word how the truck feels now is ....INSANE!! I can’t even begin to explain what a difference it is from the stock tune.What makes JDM stand out from the rest of the class is not only their expert knowledge but they take pride in what they do and take the time with their customers. Which ultimately provides a great customer experience.I want to say thank you! to Jim sr and Jim jr. You guys did and absolutely amazing job!! I will NOT be going to anyone but JDM for all my F150 service needs because this family treats their customers and it’s vehicles with utmost care and 5 star service.See you guys soon..Rich L.

I dont recommend dealing with these gues specially if you are overseas, i have bought 1200 hp jdm package for my shelby gt500 and since payments i have waited for almost more than three months then after finally i have the package, found that two of the rods have error from factory which cost me alot time and money.I wish i didnt deal with them dont recommend you to go through what i have been there

Great tuning for my saleen mustang I live in Ga.and these guys worked with Fast Lane Performance here in Canton Ga.to put a SCT tune in Saleen Mustang runs great the tire shop is going to love me.

Vary confused why the name is JapaneseDomestic market but they only work on mustangs

Just leaving this review to make up for the idiot below me that doesn’t know how capitalism works.

Awesome tuning and dyno

Yea they are the best around!!
