I highly recommend Drew to work on your Mustang. He lowered my 2019 Mustang GT. Did an excellent job as usual. He worked on my 2004 Mustang GT in 2014 by lowering and exhaust work. Also did a great job back then. I drive one hour to get to Drews workshop and had been well worth it. He even pointed out flaws that my car had. I highly recommend Drew to work on your cars.

Drew is great, takes time to explain things and also help with future plans for the car. If you have a Mustang and looking to do work to it, look no further.

Went to see Drew about getting some upgrades on my mustang, he is very knowledgeable,takes the time to help you also understand whats a good idea or something thats not. As any good shop hes busy but took the time to respond to calls and emails. Did many upgrades, suspension, exhaust, headers,clutch and flywheel, supercharger upgrades, cooling system and tune. Very happy with everything, he was very reasonable on price, the install of everything was on time, the work was clean, very professional. The car has no issues, fast and fun. If you guys are looking for a good Performance shop for Mustangs I recommend seeing Drew.

The customer service I received from D Mark Performance is what the world needs more of right now. Drew made me feel like I was his only client, stayed hours late due to massive update and still patiently waited to inform me of all that he did to my car. Thank you for the knowledge, great service and tune!

Drew does exceptional work and is great at explaining whatever you need. I will definitely be coming back to have him help with more upgrades on my 2004 cobra.

Drew was awesome to do business with, very professional and easy to talk to. Called him up on what I wanted done on my mustang and he had no hesitations at all on the task. I will definitely bring my mustang back for any mustang related work in the future!

Drew is a great guy who knows how to work on performance Fords. He goes above and beyond to help his customers. Never had a bad experience and he also helps support the local Mustang clubs.

Drew was awesome at explaining the problem and the solution. When I asked questions he explained everything. He’s much more knowledgeable than all the mechanics at a Ford Dealer along with great pricing. Had my spark plugs changed and pump replaced and he’ll be replacing a pulley along with the supercharger belt.

Thank drew. Great job tuning and communication. As another shop owner love to find people to do business with like drew.

Very impressed with Dhruva. He dyno tuned my 95 Mustang and it is a whole new vehicle. He was fast, professional and very communicative about the whole process. He also answers his email which I find to be a huge plus. Really glad to have found a performance shop that can do anything Mustang like DMARK can. Looking foward to going back for more.

Just had my clutch upgraded to a Spec 3+ in my 2017 S550 Mustang. Drew at DMark Performance does solid work and fairly priced. Still into break in but car is running nicely. Very professional and decent guy who obviously takes pride in what he does. Great shop and service. I unreservedly recommend him for all things Mustang.

Great experience with them. Very professional and knowledgeable.

Great customer service and great turn around time as well. Not to mention Drew does quality work with a lot of attention to detail. I got my oil pump gears and crank gear done from him for my 15 Mustang GT and will be coming back to get more work done for sure.

High quality work ! Thank you, Drew! He installed my Kooks long tube headers, Steeda sway bars and Roush spoiler on my 2016 Mustang GT. Amazing work done! Great customer service, very professional! I drive all the way from Orland Park, because of the work he does and the good reputation he has. Thank you again! I will be back for more mods in the future !

Drew is a pretty good guy. Had a noise in my Mustang and he hopped in to hear it and immediately knew what it was. We had a whole gear set ordered because thats where the sound was coming from. Turns out it was just the pinion bearing and everything else was fine after cleaning. I was only charged for the bearing and labor and although it took longer than expected, he still only charged half of what another shop quoted me.Seems every mustang tuner is far away including Drew but Im glad he works well and is friendly. Looks like hes my guy.

Drew is a hard working guy and gets the job done. Dynoed over 10 cars here. Will keep coming.

Great place to take your Mustang or performance Ford. Always quality work for a great price!

If you own a Mustang or any performance orientated Ford this is the place to take your car!

Best CAI for your coyote powered car

Drew is the guy that you want to work on your car. Crazy attention to detail.
