Want to give a shout out to kaotic speed for getting my hellcat to amazing power! Great customer service! Definitely would recommend this to many if you are looking for amazing power and professional work

Had a different tuner work on my truck and it wasn’t right, took it to Shane and he had it running great and it felt like a new truck once I got it back. Shane did great work and was very reasonable. I definitely will be going back when I start on other projects.

They do good work but good luck trying to reach somone on the phone.Ive been trying to reach these guys for over a week now to no avail

In short Shane is very capable and good at what he does. Reasonably priced for the level of expertise you receive. Ive never had any issues with his work. He did some work on a G8 Pontiac for me and got it back to me next day.

Shane and Shannon are the best! Very professional and maintains great customer service! Never had any problems with any work done, and Shanes insights helped me make the best decision on my car. The entire crew does great work. Youre in great hands here. My car is always done in a timely fashion. Never going anywhere else

Very honest and professional. Will definitely go back.

Shane and Shannon are great people! I have known Shane for over 18yrs, he’s never been anything but honest with me and has worked on several of my cars with great results. When it comes to anything LS related he has a wealth of knowledge and experience. Cars are mechanical and anything can happen however I always trust Shane to stand behind his work and that’s why I choose Kaotic Speed!

Just brought my 2019 Honda Type R in for a tune with Shane. Its like a totally different car! So much more responsive and a blast to drive! When you think they have masters of the LS world with how happy we are with our WS6, they go and blow my mind with my Honda. They are seriously the jack of all trades. Wouldnt take any of my cars anywhere else period. They always go above and beyond and their success confirms it. Is there anything they cant do?! These guys are the best hands down.

Had to have my car towed there and within the day they had it driving again. Affordable prices and expert care. I dont entrust my car to just any shop. Thanks kaotic speed!

We had our WS6 worked on here. New motor runs like a top. Just won the 11.5 index class with it at Import Showdown. It’s the most consistent car we have ever had. Couldn’t be happier. Car will be back for more upgrades after the holiday and in the future for sure. Can’t wait. Love every minute of working with your guys. Top quality shop.

Customer service is outstanding. Had a motor put in my car by them and runs top notch. I will definitely bring any car I own to them in the future. The staff here works extra to make deadlines and the facility is always very clean!

Shane and Shannon at Kaotic Speed are absolutely great to deal with and are very professional. The definitely know what they are doing. If your looking for a great performance shop on the southside of Atlanta look no further.

Love my new corvette upgrades!!

I took my ls1 silverado there and they worked with me on really opening up my engine build. They did a masterful tune and the truck drives so much better now. Their customer service was great and kept me updated on my truck and didnt make me feel like they got mad if I asked questions like other shops have done in the past!

I have heard nothing but how awesome and nice Shane and Shannon are.. And how Shane does some excellent work.. plan on taking my TransAm up there soon and do some work with them. Can’t wait to see what happens..

Kaotic speed is the best. Between the owners and staff and the experience we had working with them on our car we will only use kaotic speed. Thank you all for doing a awesome job.

Kaotic speed will get you up to top speed. Great performance upgrades at affordable prices.5 stars!

The staff is great and knowledgeable. They fixed my truck after three other shops couldnt. Wish I would have went there first.

Great folks to deal with. Very nice and professional. Yep I will be backThank yall again.

Great to work with. I went to Kaotic Speed to get my Mustang dyno tuned this year. Spent a few hours on the dyno never once was I rushed during tuning adjustments. They filled up my nitrous bottles and hooked me up on the price. I will be a returning customer.

I have used KS many times. Great people, professional and their knowledge is unsurpassed. Will definitely use again!!

We have personally known the team for years. From Jeeps to Tundras and motorcycles- if it has a motor they can help- always with a smile. Fully recommend them. Thanks, Greg

Shane and the crew have worked on my Diesel truck and my supercharged LS. Both times the work was perfect and customer service is great

I dont feel like just another customer, I enjoyed the personlyze service.

Great people to do business with got my Cadillac running great thanks again!

The service here was AWESOME! They have gained a lifelong customer!

Great team who knows exactly what they are doing! Awesome attitude!

The staff was very knowledgeable and professional during my visit!

Service and employees are excellent at Kaotic Speed! Building and racing run in their blood! Want a boost call Kaotic!

Kaotic speed crew was amazing did an awesome job on my truck

Great place to to race fuel and nitrous and can also get ur car tuned and put on the dyno for more power, friendly staff and knows alot of knowledge about making a car go fast keep up the great work guys

Shane Speed is the best around. You wont be disappointed. There isnt anyone smarter or more professional.

I have a 1972 GTO I took it two three different garages they kept it for two or three months wasting my time and my money I took it too kaotic speed and no time they have me a new motor to rewire the whole thing and then a great tune up the best tune-up I ever had dont take your car to another shop its just a waste of money and time they take care of business there I had not one problem out of this car and is run the bestest ever had since I bought this car they have great fast service good prices

I have never dealt with any business that has been so friendly, professional, knowledgeable etc etc. Myself and my wife have a 2001 Pontiac Trans Am WS6 A4 that has been to kaoticspeed since we took ownership just over a year ago. We just recently put it in a 11.50 index race @ Silver Dollar Motorsports Park where we took home the win. Car was consistent and went A to B all day and Shane was there throughout the day to help and give advice on what might work better for the setup than what I was doing which helped out. We look forward to the future with this shop. If youre in the area and have a late model GM vehicle, give them a shot and you wont be disappointed.

A1 customer service, quick call backs and top notch work!

I’m a owner of a 2014 Chevy SS, I’m lightly modded, nothing major. I took the car to someone I know and got it tuned, well that was a terrible idea. They messed up my tune. People recommend me taking my car to Kaotic Speed. I decided to take it there! I met Shane, and he gave great customer service, he was very informative about everything. I definitely felt like my car was in great hands! Kaotic speed let me know when my car was ready for pickup. I went from 402whp from the other place to 445whp with kaotic speed. The trans tune they did on my car is awesome. My car went from slow, lazy shifting / response to being fast and very responsive. I am now a lifetime customer ! I highly recommend kaotic speed!

Thank you. I am in love with my Z06 all over again!!!!

Quality work and great customer service!!

Great place to pick up race fuel

Does sloppy work. motor was held in with zip ties. shotty grounds.

Thank you guys for all that you do for me and my fleet.
