Thanks, dark side development came up when I did my research and they indeed have SQ7 tdi tuning - good to know that are an established tuner in the community. Will look into the other two companies. Would be good to get some feedback if any owners had their SQ7 tuned as well.

Hi all, just joined and looking for some advice on SQ7. I’m considering SQ7 tdi as a possible replacement of my GLC63S (unfortunately not the petrol engine due to budget), just wondering if anyone had their SQ7 tdi tuned (remapped or with bolt on box?), what sort of performance increase and the cost? Thanks
