When I finally got the Demon together and ready for Dyno tune. I “Wasted” an entire day waiting on them to fit me in. They were some race buddies doing me a solid so I did not have any real leverage on schedule. It was a day I will never forget. Pure exhilaration at the very same time as pure panic! They were merciless, I spent years getting to that point and I thought to myself these boys are going to destroy all that effort in ten minutes. Every time they let off the gas and I watched the car torque back the other way and settle on the rollers singing the song only Dyno rollers can make I would unconsciously let out my breath, not even realizing I was holding it during the ramp up. @Maxcustody you will never regret it! Be patient, take a book and some groceries, I took a lawn chair so I could sit outside and await the moment of truth. I snacked and read for hours till they rolled her up and prepped for the pulls. You gotta be there guy! Enjoy it!
