Working on a new build and need to sort out the tuning side of things. Has anyone here worked with 5 Star Tuning before? I see they sell the devices with custom tunes pre-loaded, which sounds super convenient. Just want to make sure they are legit before I pull the trigger.

They are totally legit. I got an SCT X4 from them pre-loaded with a few different octane tunes. The difference in throttle response alone made it worth every penny. You won't be disappointed.
