Funny story, when I got my tune I was nervous too. Got boost leak test, fixed the leaks in 5 minutes (needed new clamps), and hopped on the dyno. Felt good.
Tuner comes back 30 minutes later and says the dyno broke........ anxiety all over again.
You can just say your car made so much power the dyno couldn't handle it
