I purchased the stage 2 tune for my W211 E63 and that tune is amazing,Thanks Lukas for the excellent customer service!

I ordered tune by web site. Car runs great. Easy installation. Good support from Anthony. I highly recommend this tuner. Thanks guys

Poor service, poor value, and not professional. (owners response below is just a testament to their lack of professionalism, cant handle any situation without trying to say its the customers fault).

Toni at RaceIQ was great to work with,very knowledgeable about the tunes. If you need a tune call Toni at RaceIQ.

Great performance shop for all cars european. tony is the tune master and he takes so much pride in his work.

Tuned my 2020 Si in 10 minutes! Got rid of the rev hang, starts in sport mode, got 2-step... the list goes on. Absolutely great customer service, too. And on top of all that, the perks of going back cant he beaten!

First time MB owner (E55 AMG). Decided to get a Stage 2 Performance Pack and was told by majority of members from various forums that RaceIQ is the best. I am writing this review to confirm, Facts! I purchased a remote Tune from Tony and he was communicative andProvided a tume promptly. Once loaded and I driven the car, I could tell instantly, this guy knows what he is doing. It felt like I had taken the car to the Dyno to get tuned. The gears shifted on point, and the power and sound left me in smiles amd expletives from excitement. Definitely will become a loyal customer for years to come!

My SL55 was recently upgraded and outfitted with a VRP stage 2 performance kit. The ECR tune was overseen by Anthony Lawshee of RaceIQ. The AMG transitioned from a contender to a outright Champ! Anthony is to be commended for his personal attention to this project.

Purchased a stage 1 tune for my 2005 E320 CDI. RaceIq worked directly with my mechanic to get the tune installed and provided all support needed to make sure everything worked perfectly. The car is now running way better than stock and still gets great MPG.

Great place, lots of help and very friendly. Highly recommend!

Alicen was a huge help, i messaged her on Facebook with a question and received an answer almost immediately. Gotta love race iqs support 👌

After entrusting Tony and his team with my 2016 CLS63 AMG for maintenance and performance work, I’m positively a customer for life! Not only are they knowledgeable and easy to talk to but they are quick and efficient in their services/communication. More importantly, their prices are great! What’s more, they go above and beyond each and every time—my last visit, for example, they topped off my wash fluid and coolant reservoir even though this was not part of my maintenance. In summary—it’s a friendly atmosphere, where Tony and the team will take time to walk you through the details and help guide you on your performance journey. For us local to RaceIQ—we should consider ourselves very lucky! My CLS is running in tip-top shape and fast to boot.

Anthony was very professional and easy to deal with. He made the whole process as simple as possible. The tune was fantastic and I have fallen back in love with my car. They nailed the first time impression and have gained a life time customer.

Anthony and Lukas were great to work with. I messed up my initial attempt to flash my car. Anthony, while on vacation, put me in contact with Lukas who promptly fixed my issues. The tune is awesome and my s55 is running better than ever. I cannot thank them enough and I can’t rate highly enough. Raceiq has a customer life and I’m looking forward to further business as I add some more mods.

I got my CL55 (M113K ) Remotely tuned and they did an awesome job! Car mods 80mm SC pulley + Intake Spacer + AEM Filters.

Do not hesitate to do business with these guys. Anthony knows what he is doing, and Lukas will go out of his way to help you out. They care; plain and simple. 100% legit.

RaceIQ tunes ROCK! Put in a Stage 2 Tune in my CL55AMG and the exhaust note is louder and way quicker off the start and throughout. THANK YOU 💯 💨💨💨

FIRST TUNE FOR MY E55 WAS GREAT AND ANTHONY WAS AGAIN GREAT TO WORK WITH FOR THE MODIFIED TUNE FOR MY NEW HEADER INSTALL. I WILL ALWAYS RECOMMEND RACE IQ HIGHLY. ATTENTION TO THE CUSTOMER IS TOP NOTCH.

After many days of researching different tuning companies for my e55, I chose to go with Raceiq. Tony was amazing to deal with. He was very informative and answered my questions very fast. Hard to find customer service that good nowadays. Car pulls way harder, and I will direct all of my future tuning to Raceiq 👍

Super friendly and quick answers. The software is a lot better than the one I had before. Highly recommended.

Tony has always been great with any questions Ive had regarding my car. He provides customer service on a very personal level which isnt found at many places. The tune was dead on point which saved me the hassle of going back n forth to hahw the right tune.

Shout out to Tony at race iq!!..hes simply the best!..I had a bad tune and heat soak issues,so I was only putting down 440whp and 460rwtq with a tune from another company and 77mm clutched pulley....took it to Tony and he installed a 74mm fsp..Underhood ice tank...updated plm heat exchanger...replaced my thermostat housing...did a ecu and tcu tune....and put on new front brakes,rotors, and sensors....after Tonys magical touch I am now putting down 476whp and 618rwtq which is rare with stock manifolds and stock throttle body...tony definitely did something magical!!..he even picked me up from my hotel!!!..now thats service!!!!

My E55 ran like a bag of sand, seriously appreciate these guys helping me out and finding out what the real problem was! Genuine and friendly staff and they have some serious stopping power when it comes to their Tuning and Performance!! Thanks so much guys I appreciate you guys so much! I now enjoy my car again!

Race iq has done ecu work on a couple of my cars. Top notch work every time! Customer service is always a1. Probably the best I’ve ever dealt with! Thanks again for everything Tony! Will always recommend your work and services!

The most professional and dedicated company I have ever been lucky enough to do business with. Very responsive to emails or messages but more importantly the products they provide are second to none. Im very happy with my E55 AMG Cams and ECU & TCU Tunes. Thank you Anthony!

The tuning for my AMG is great. Everything worked smoothly and the support was perfect. Every time again!

Tony went above and beyond with tuning my C63, you can definitely feel the massive power increase. His customer service was incredible and I will continue to go with him and RaceIQ for any of my tuning needs in the future.

Tony at Race IQ has been extremely helpful and gone above and beyond with the tunes for my E55. I will continually support Race IQ with all of my tuning needs and more.

By far the best tunners i have ever encountered very helpful quick responses very informative fast updated tunes when requested.

Best Tuner in the car game. A+++++, Had patience for my 20,000 question. Woke up my E55!

I bought a tune from Riq, but since I am in South Africa, I opted to buy a galleto tuning cable locally. When I tried to load the tune it failed, I then got another cable but that also failed. Tony logged in remotely to assist. Still could not get it to work.He then refunded my money but at the same time, shipped a galetto cable to me ( normal shipping to South Africa takes just under 2 months ) during that time I got an Ec tune. When I received Riq’s cable I loaded his pops tune. I must say that I am truly impressed, the pops tune is pretty neat. I highly recommend Riq as Tony is a proper standup guy, communicates well, has a good product. As I had a Ec tune already he even allowed me a favourable price to load his.He is a honourable businessman, most people would not refund, but he has integrity, I wish more companies ran a business like he does. Great product and excellent service.

RaceIQ did a phenomenal job of tuning my 2004 Mercedes Benz E55 AMG. The car performed beautifully and the customer service was excellent. Highly recommend.

I got an ECU tune for my 2010 E550 N/A. The results were noticeable, more gainz for sure. Great guys to work with.

Tune Mercedes EGS 52 TCU, great job.

Anthony knows whats up, he not only has the knowledge but he has the know how. Go to this guy for all your tuning needs.

.Thanks very much Anthony. Excellent service and results from E55 supercharger pulley and tune.

Best tuning company!

Outstanding!!
