Auto Performance Modifications

I am lucky to drive a Subaru with a handful of shops you can rely on in the Chicagoland area and this is one of them. There are only 2 other shops I would ever take my Subaru to so that says a lot. This place has great customer service and they have always pulled through for me whenever I bring my car in. They go above and beyond to fit the needs of the customer and that is what brings me back. They are flexible with me with Saturday drop offs and even after hour drop off and pick up. I work Mon-​Fri 9 – 5, so it is hard to come during their hours, but I trust them as they are honest and knowledgeable. I dealt with Mark before, and Ian the last time, both which are great guys.

Was referred by my good buddy Ian W. to check out this shop. All this time I been ordering parts online, shame on me for not supporting my local shops. I will say its rare that i get a great experience and customer service nowadays, but Mark and staff are great. I have been to the shop half a dozen times already. Got the APM blast plates/​transmission braces since i was installing a new clutch and the shifts are super crisp and loving it, there is an increase in cabin noise but who doesnt love hearing the car do its thing with all other bushings and mounts. Mark takes the time to help, listen and make recommendations. I never thought of stepping foot in a mechanic/​performance shop ever again, but my relationship with APM will always be there. Keep up the great work guys!!! Thanks for helping me with my build… I have a mechanic I can trust now, and I know of many more guys from the forums that go here. Support your local shops, especially this one! Your car will thank you for it!!!

Mark has always taken care of me! They made an intake for my car and tuned it! Everything these guys do is awesome! It’s a wonder why they’re always busy. They may take some time to get to you but their work is top notch!

I have been to many shops in the past and I have always had an issue with them when it came to pricing, availability and with improper installation that comes with the best excuses. Not a single time has APM made up sad excuses. I have brought my 13 WRX to them for small stuff like oil changes and to big things like tuning and I can confidently say this is the best shop I have ever went to. The guys are honest and help you out as much as they can. Even when they are booked solid and busy they will always do their best to get you in and help you. My stamp of approval may not matter to you but I bet if you try them out even once you will see why they get all 5 stars in my rating!

This shop is incredibly amazing, trust worthy shop, they are honest and straight to the point. Mark @APM is very helpful. He helps you out and answer any questions you have and give you his opinion from his personal experience. One of my best experiences, I had at this shop. Will definitely recommend this shop to all tuners and even people who are looking to perform just maintenance work. APM Tuned is Hands down the best shop I’ve been too. keep up the great work!

Great shop to work with when it comes to Subaru’s. I had their Aluminum design Quad-​tip exhaust installed and very happy with the product. I will definitely do business there again.

Cool shop. Had them do suspension work on my car. They did it for $ 150 less than all the other performance shops quoted me and and the job came out great.

Working in the car business, its hard to find people whose advise you can trust. A lot of guys will try to sell you parts you don’t need and tuning services you can’t possibly afford without a mortgage (looking at you AMS).
Mark is the manager, very knowledgeable, easy to talk to, and doesn’t charge and arm and a leg for great services from his professional crew. They work on tons of Subarus, but they know how to work on Mitsus, BMWs, etc.
I had a tune done on an EVO 8, with an EVO 9 turbo that was running rough. 2 hours of tuning and adjustment, and the car ran strong and I knew I had someone to bring the car back to for future services.
Big thumbs up for the APM team!

I’ve come here for multiple services and inspections, I always leave satisfied and they have one of the best prices around. You can expect to set up an appointment a lot sooner than most shops and they make you feel at home.

A diamond in the rough. This place is off the main street but you will be glad once you find it. They set me up a fully custom exhaust and ecu tuning. The exhaust sounds even better than I thought it would. They have tons of upgrades available and can do almost any type of service. Also, the employees were very friendly and helpful with showing me all the options for my ’08 wrx. I will definitely return for some more upgrades.

Mark and APM were very communicative through email in helping me to diagnose my problem. This was my first trip to APM. I was treated really well. In fact, even before I could get out of the car, Mark came out to greet me and looked at my issue. Sure enough, I needed some major work done. The guys showed me exactly what was wrong and explained to me the various options I had. Then, we set out a timetable for the repair, and Mark took me to Enterprise and made sure I got a discounted rate. Best of all, the car was ready over a day early, and the repair is solid. They did not exceed their estimated cost. I have a 2008 Subaru STI and wouldn’t take it anywhere else for servicing.

I have a BMW MIII. I can’t tell you one thing about the mechanics of a car so a few years back I found APM and became a loyal customer of theirs. If Mark at APM told me that the dingbob on the trufflehammer needed to be tightened, I paid their company to tighten it. If the wingbat on the frenchfry had snapped, I had them replace it. That’s as much as I know anyway.
My experience here has been a painful one. This is the most unreliable shop I’ve ever known. You may or may not get your car back on time. I mean to say that they’ll tell you to pick your car up in 2 days which will often turn into 5… 6…7 days and a few times for me, 2 weeks. This had happened so many times that I eventually began to expect it. When I did get my car back, it was often not quite fixed. It usually was back in the shop for the same problem within a few days. As for reliability in service, I can’t judge the work quality, but my guys at BMW frequently referred to them as, «the hacks,» whenever they took a look at my car.
APM often impressed upon me that they were doing me favors with prices. I won’t write a long review on behalf of my husband, but I will say that he followed up on the work APM had done on his Cadillac only to find that they had been lying about prices and trying to rip him off. This was our last time doing business with this «company.»
The above mentioned horrible customer service, sketchy work, dishonesty, unreliable completion dates, and price gouging… oh, and the porn in the bathroom, is hopefully enough persuasion for you the reader to find better places to do business. I recommend Performance Werks in Aurora.
