Mo's Speed Shop, LLC

I can't say enough good things about the team at Mo's Speed Shop.

From the initial conversation around my issue to keeping me informed through the process, to fair pricing and explanation of next steps during delivery; everything about this shop is perfect.

I had a clutch failure on my 2014 GT500 and these folks made me feel comfortable throughout the process. Helped me to fully understand the cause, issues, and helped me sort out a few other things on this 10 year old car. They returned it to me in perfect condition and treated it as their own. The car drives 10x better than before it went in, it feels great; like it should have been all along.

Exceptional service, exceptional work. I will be a lifetime customer.

Thank you Jeff, Ryan, Mary and the whole team at Mo's for fixing my car RIGHT.

Great guys very knowledgeable help get me out of a bind situation at 12 o'clock at night walk through the tune problem to get the truck drivable and willing to work to finish up the tune at a later date. Highly recommend them after talking and going through the process.

Absolutely best experience I’ve ever had with remote tuning. Was being tuned by someone else with nothing but issues at least 40 revisions. They took care of it in 3. Car runs perfect. 2004 gt

I recently ordered a Marty Tune for my Town Car and it's literally everything I wanted. I'm even getting 2nd gear scratches! Thanks again for offering such a service! Excellent customer service too, I send an email and a few hours later, I get a reply.

I have purchased tunes for my Crown Vic from Marty, both as an automatic car and now a manual swapped car. I have been more than pleased with the results from these tunes, and even more impressed with the customer service and personal support I received from Marty and his team at Mo's. He has helped me tremendously over text and phone with everything from diagnostic issues to fabrication questions. Marty is courteous, professional, patient and definitely maintains an interest in the success of his customers.

Jeff is a Great guy very helpful. I had my car tuned almost 10 years ago and I lost the chip for the computer. Jeff was so organized he went back and reproduced it for me. I was pleasantly surprised.

Very Professional to work with! Very responsive and informative from the first time I spoke with Marty about getting a custom tune for my vehicle. He told me everything that was needed on my end for him to properly tune my car and responded in a timely manner to questions I had leading up to my first tuning session. The night of the tuning session everything went smooth. I could not be more pleased with the professionalism of Mo’s Speed Shop (Marty & Jeff). Highly recommend to anyone. Great crew!! Look forward to working with them with future projects!!

Mo’s Speed Shop is Fantastic. Jeff and Miller have helped me with multiple issues, electrical and mechanical work, and a Dyno Tune. They are professional and amazing at what they do.

Marty and his homies here will get your car ripping! He’s super knowledgeable and fantastic to deal with. Even after hours, best shop I’ve ever dealt with. 100000000% recommend. Would give more stars if available!

I can not praise this man enough. He is a legend in the Panther world (and others, I'm sure) & now I know why. I've read all over the Internet about this guy who does these "Marty tunes". Tons of great reviews from everyone who got one. So, after 4 or 5 years of wanting one, I went ahead & shot his shop an email. Keep in mind, I'm still pretty new to the Panther platform & NOT a mechanic. I'm just a chick who likes to drive fast & doesn't mind getting her hands dirty. After a summer of serious electrical issues, I figured if I needed a new PCM/ECU, might as well get it Marty Tuned. He emailed back suggesting I get the electrical issues solved first. And that's about it. So, I did. A couple of weeks later, my Marty Tune was on its way. SUPER EASY install, responds to all of my emails, straightforward, & to the point, I would relocate across the country just to pick his brain. My car runs better than it ever has & I LOVE IT!! BEST MONEY I EVER SPENT!! THANKS, MARTY!!

I am absolutely pleased with the service and the knowledge provided by Marty. I do not live close to the shop however when it comes to car tunes I can most certainly say this is the best person to talk to and do business with, especially with panther platform cars. Distance is no challange, I have gotten multiple tunes from Marty within the past 4 years, and if something is wrong he will make it right, that is true customer service! I am pleased with the quality service that Marty provides. Thanks Marty!

What can I say that hasn't been said in the Panther Community? Marty and Crew are the BEST at Tuning the Panther Platform 4.6!
We Manual Swapped my Crown Vic and Marty sent out the SCT Tuner w the tunes loaded and it was Plug & Play from there. I made a few changes later and he emailed me updated Files to upload.
His Customer Service is excellent and they will continue to get my business

What a great experience. Scheduled a time to come in. Waited just a few moments and one of their managers was able to take a ride with me and we fixed the issue on my Cobra in about 60 seconds. Just a little vacuum leak and they found it and fixed it for free with no questions asked.

I have follow up visit planned for some other tweaks I’m doing to the engine and I know I’m in the right hands with this company. Thank you!

Just to say, this is the only shop I will take any of my custom or modified muscle cars to. They are courteous, quick, and professional. They always take their time and discuss the problems my vehicle has and what all the possible solutions may be. I had originally brought my '03 Town Car here (Long tube headers, throttle body, bash bar etc) they tuned the car and after a day knew more about it then I did. I recently started bringing my '06 Mustang GT as well. All the same they were quick, and considerate. They found a couple of other issues with the car and gave honest advice on what they would do to repair it, all in all I have yet to find another shop that listens to my concerns and never tries to over complicate a small problem.

I can’t say thank you enough. The guys were timely and very thorough in answering my questions during the process of tuning my 4.6. It was so easy. We exchanged information, made an initial transaction for the SCT device, and finally set up a time to import the tune and make some fine adjustment to the unit. The process went exactly as it was explained to me by Marty. I would do it again without hesitation.

The Marty tune loaded onto my Crown Vic transformed it into a much more pleasant and lively vehicle to drive. But not just that, Marty goes the extra mile to help out and the service is second to none. He helped me resolve an issue with my programmer (despite it being outside of his remit) and saved me $$$ and for this I’m very thankful. Highly recommended.

This guy tuned my 2009 Grand Marquis and it was AMAZING. He is a great person and his communication with customers is 10/10!!! He will answer questions as well. I DEFINITELY recommend this company. Love them!!!

These guys helped me out big time with a busted weld! One guy recognized exactly what the pipe come off of and what the car does that made the weld give. With that quick display of knowledge and seeing all the performance cars in and around the shop, they gained my future business and I would highly recommend them to anyone! Hands down the most solid shop I’ve ever been too!👍🏻

Jeff is a great guy. I was heading to a Mustang meet and ended up on the side the road. After about 1hr. and a few other car community people stopping to check. Jeff from Mo’s Speed Shop just happen to drive by with a car on the trailer that he drove all day to get. He turned around to come back to check on me, after some troubleshooting he end up unloading the car to put my car on the trailer to take me home.

Knowledgeable, professional, and a genuinely nice guy. Came to Marty with some tuning needs after a motor swap. He got me setup with brand new packaged tuner and priority shipping. Arrived on time and followed the easy to read instructions. He texted 30 min before our first session to say he was ready and 46 min before our second. Heres some easy motivation to complete your project knowing it’s in good tuning hands with Mo’s Speed Shop. 5.5/5
