GRDTuned

They did an amazing job installing parts on both of my cars. They took responsibility for any inconveniences that occurred and they took immediate action. Chris is an amazing worker. I’d trust him with anything on my car. He helped me out all the time and saved me a lot of money! I love this place and will always go here if I own a German vehicle.

This shop is so nice and friendly! I don’t know much about cars and they’ve helped make some amazing recommendations about what I can do to make my car more enjoyable. So far I’ve had them tune my car, put in a new intake, add new spark plugs and coil packs, and do a turbo muffler delete and everything went smoothly. Cant wait to have them do more work to my car these guys are awesome!

I've been a car enthusiast for years, and GRDTUNED has earned my loyalty like no other shop. From the moment I walked in, I was impressed by their dedication to helping customers choose the perfect performance products for their cars. Their expert advice and extensive knowledge in performance enhancement truly set them apart.

I've had several upgrades done at GRD Tuned and each time the results have exceeded my expectations. The team’s attention to detail and commitment to quality are unparalleled.

Their expertise in working with Audi and the exclusive products they offer from APR Tuning are top notch. They also work on VW, BMW, and Porsche.

Their services are also competitively priced and expertly handled. Highly recommended!

Really great Shop I had a good experience with everybody over there. Everyone was very helpful and very nice. Also they did a great job changing my brakes and my rotors, front and rear. I will definitely be coming back. Had an A1 experience.

Hard to find a place that is knowledgeable about German cars. My wife has a 2013 2.5L Beetle and I was surprised to find out how many places I went to that were uncomfortable working on simple maintenance. Customer service was great and they were very easy to work with.

Super good guys even on a Monday when people are usually cranky. Very knowledgeable about their products. I would definitely recommend this business to others. 😊 Stage 1 APR Tune & Throttle Booster on my 2015 Audi A8L V8 4.0 T. Ready to blow minds & stop watches 💨💨💨 thx guys.

Was just in having my 2019 Tiguan R-Line tuned and exhaust added. Scott and Chris were awesome. I couldn’t think of a more professional on the level place to get pro work done on your car..seriously.
They were very attentive to what I wanted snd offered solutions that made sense for me. I’m a fan and a customer now!

Brought my 2016 S6 in for an APR stage 1 ECU and TCU tune. Process could not have gone smoother. Chris advised me on the different options to chose for the tune based on my availability to different octanes and driving habits. While I was there Scott got a call from APR to let them know Monday will start a 10% off discount. Unprompted he helped give me that discount a week early. Really great guys, will be coming back for more performance upgrades to my S6!

I just brought my 19 Audi S3 for Dsg,Haldex motor oil services and alignment and APR stage 1.Ecu & Tcu .talked to Chris and his really knowledge about his job and explained me everything what they did to my car and how to get more power out of the 2.0L
Great customer service

Great customer service at GRD and great work too! GRD took my Golf R to stage 2 in '19 along with installing some other bolt-ons. It's August 2020 and the car drives like it did when completed, zero issues. Thanks everyone at GRD!

Great experience. Had an APR+ tune and intercooler installed on my Q3. Brought it to another shop who did not communicate with me or APR and was unable to install the tube. Called up GRD and Chris was super knowledgeable and able to get me in quick. They even offered to address a couple small things without me asking.

I called 2 days ahead ask about the stage one upgrade for a 2014 A7 the guy give me the info I said great when can I come he said for that you can actually come on Saturday and it will take about half an hour so bam woke up made the 50 min drive pulled up Guy was super nice super informative 30 mins later I was driving completely different car and guy!!!!

Had a issue with my 10 year old ARP tune.. They took care of it in 30 Mins on a Saturday. Very Happy, Nice guys.

The absolute best place to get your VW/Audi serviced/tuned anything your heart wants. This is the best shop in the midwest. Best prices, best work, best results. Will go no where else to get my car worked on.

The staff was awesome and the APR tune was perfect and put on quick with no hassle. My 2011 Tiguan has never been this good all around.

I've been a customer since late 2020. I've mainly dealt with Chris and Scott. They've always been professional, honest, and most importantly, KNOWLEDGEABLE. Tell them what you want, and they'll let you know what you need. Whether you're going for performance or simple maintenance, they'll give you prices up front so you know what you're getting into. I will continue using them.

Great shop, friendly helpful staff, will always go out of the way to make sure you are satisfied.

Chris and his team were Awesome. I had my 911 Turbo tuned (APR) ECU and PDK. They did awesome job. The tune unleashed the monster that lives inside my car. Thank you so much GRD Tuned.

I have an Audi S6 they did a APR engine and transmission tune. Change plugs and few other things. The service was outstanding. I would recommend everybody to use them.
