I’ve made sure to read every comment in this thread bc I know yall have way more knowledge about these cars than I do. There’s been a lot of great point’s brought up about stuff I hadn’t even considered or thought about. I have faith in this shop but I’m definitely not going to have the guy run my car if I don’t feel comfortable or if I know it’s not going to be safe for the car or anyone around. I’ll post an update on Friday with the numbers the car made just for the hell of it in case anyone is curious. Thanks again for your help.That is a very valid point. I'd make sure the dyno operator knows that the OP doesn't know the state of the tune nor if there might be unknown issues with the engine (hopefully not). In other words, operator proceed with due caution. As much as possible.
