I called for some basic info and quotes. I was so surprised to have on the line a gentleman who was eager to answer any and all questions. They took the time to share their own knowledge and experience about my model of vehicle.This one conversation let me know that i was dealing with a company that was passionate about their customer base and are extremely knowledgeable about the vehicle they work on.Thanks for all the help! I am looking forward to lots of business in the future

I had been working with Kellen since I bought my CLS550. I learned he was no longer there and Mitch took over. Mitch and I communicated via email in regards to installing their Diverter Valve Kit on my car. He was able to squeeze me in before I left FL.As Kellen always had done, Mitch gave me a tour of the facility and we checked out some pretty neat cars while my car was being worked on. I even got to meet the living legend, Hartmut Feyhl!After my car was done, they washed it and I was ready to hit the road. Once I accelerated, I heard that “fart” … man it was so satisfying!!!Thanks again Hartmut, Mitch and Team for an amazing job! This was my 3rd Renntech Upgrade and I’ve been super happy so far.

Awful customer service. Will make it hard to even return parts even when they ship the wrong part! Don't believe me read their reviews. Found the correct BOVs for my 63 and 110.00 dollars cheaper.

Over rated here in the US. The worst customer service. Tune $3000 down the drain. They blamed it on Texas having the worst gas in the US and kept the money. Stock tune was better after Dyno!! Nonetheless, they could careless.

We had some updates done on a module for our Sprinter van. We talked to John on the phone, a more helpful and friendly person you can’t find. We were overwhelmed with how knowledgeable everyone was at Renntech and how they addressed our problem and got us back on the road. We thank Dian the programmer for solving our issue. Highly recommend Renntech to everyone.

Recently purchased an AMG GTS with all sorts of Renntech extras. Even though I wasn't an existing customer, Mitchell G went above and beyond answering my questions trying to figure out what I had on my car and also helped to diagnose a fuel issue I was seeing on the car. Top notch service.

Ordered a handheld tune from Renntech via mail. Product was great and staff were very knowledgeable. Small issue with firmware but as soon as I called them to rectify, they were able to identify and problem solve very easily and conveniently.Also, then tune is absolutely amazing! Exceeded my expectations!Special that's to George for all of his help throughout the process.

We've had the best experience, thank you John, for the multiple times you've helped me with our 2021 Mercedes Sprinter. We are tuned and ready for our 6,000 mile road trip! We highly recommend Renntech to anyone ready to elevate their sluggish Sprinter!

Mitch was a excellent enthusiast and knowledgeable rep! Made the process enjoyable and exciting. E63s AMG tuned to perfection. You won’t find more knowledgeable AMG engineering. Follow up was excellent and was appreciated Hopefully Mitch is recognized by upper management for his over the top efforts

Purchased the hand held suspension module and had it installed at Renntech. The customer service and technician were very informative and helpful and would recommend Renntech for anyone looking to upgrade their Mercedes.Service: Steering & suspension repair
