First experience with UroTuning and it was not good. I waited nearly three weeks to have all of the items that I ordered in-hand while my vehicle was out of service for one week due to a related part that was not sent. All of this could have been avoided if the UroTuning Rep had been more careful when resending the missing part. I am very disappointed at the lack of communication and consideration. I ordered an O2 spacer and an ARM downpipe. The downpipe arrived quickly (appears to be direct ship), but I never received the O2 spacer. I assumed the spacer and downpipe were in the same box, big mistake. I had to leave my car on jackstands for a week while waiting for UroTuning to send the missing part. I usually make my purchases from ECS Tuning for last 15 year, looks like I need to stay with ECS.
