I just sent mine to Kory and had him unlink it. Got tired of dealing with him. He blamed my 3794 so mark took it back even though it was used. Maybe 1k miles on it and sent me a 68 stg2r for the difference. Then I couldn't even drive the truck due to how he had the vains set up. I had issues with his tuning from the get go. Kory did finally give me around a 250$ refund on my way home from marks. I argued with him for a month and he said when I can prove the tunes are the problem he would refund me. Mark did that for me lol.
