Repeat customer. 6 star. Did custom tune on my 3.0 duramax. Definitely worth it :) Came back for axle ratio change. 3.23 to 3.73 . Will be back as soon as I get the 43 gallon titan tank installed to update so my guages read accurately. Highly recommend in sioux falls , sioux city areas and beyond.
My engine light came on late Saturday afternoon and I needed to make a 12 hour journey the next day. Johnson Customs worked on my car late into the night to get me on the road and got my pcm reprogrammed perfectly. This is an amazing company who goes the distance for the customer and does excellent work. Thank you Johnson Customs, you are so greatly appreciated!!!!
You get all help what you need for tune your car or permanently remove dtc, urn off autostart. Congtatulation for the grat business what you manage.
Worked with me to clone my Body Control Module for a good price and then helped me troubleshoot further issues- all while I was in another state. Ended up needing some programming done to my ECM and that got me a back up and running. I appreciate it!!
I have nothing but praise and respect for this company. They have great customer service and they are always there when you need them. I ordered the 5.4 3V phaser lockout. My truck is now a beast. Great HP on the top end and low end. My truck started up on the first start and sounded great without any noises. I have to get used to the HP because it is very powerful. They did a amazing job with the tune that they are using. I highly recommend anyone who is second-guessing. Money well spent!! Thanks sincerely.
