Drop off to get tuned

So after quiet some time I am dropping the car off to get tuned. Fingers crossed everything goes ok, it looks as though there is a coolant leak now which was not there before.
Noticed it when sitting

in the driveway of the tuning place, not filled with confidence that everything will go ok now.

Second guessing if I should get it done but I think that I am just nervous after such a long time.

I am going to try DVS tuning after a recommendation from Shane who had his car done there and was very positive about the experience and how he took car of his car.
