The Dyno Shop

Took my 2019 Mustang GT to them after being told the dyno tune and e85 conversion would cost $1,400.00. An hour after dropping off the car my son (his car) was called and told they couldn't do the E85 conversion without a kit and the cost to tune the car would be $2045.00. They said it was more work than they anticipated. They are are called the Dyno Shop but don't know what it entails to tune a stock 2019 GT? Unfortunately my son told them okay and they did the tune. No complaints on the work done. When we picked the car up Hayden, the mechanic, said he would only charge $200.00 to install the flex fuel kit if we brought it back to them. stupidity on my part but we purchased the kit and brought it back to them. Like clock work, they call an hour later and say it will cost $500.00 and we need to bring them a card for the tuner claiming it didn't come with one. My son says okay again and brings them the card. Two days later we get the car back at a cost of $795.00. The tuner was not hooked up only the card was programmed with the settings. He said that would be extra to install and hook up the tuner. Seriously? When my son went to hook up the tuner the card that came with it (the one they said it didn't have) was in the tuner and blank meaning he only programmed the card we bought and never tested the tuner. When we installed the card Hayden programmed it was blocked by firewall issues. I called and complained to the owner (Mark) who was cool other than saying we should have just said no to the price changes and didn't seem concerned about that being a poor business practice. He arranged for the car to be taken care of on a Saturday and said the tuner would be fixed and installed for us in the dash as it is supposed to be. My son took it in and it was fixed however Hayden refused to install it in the dash as Mark promised. $2800.00 bill and that's the service you get... Buyer beware. They can tune cars but it will cost you double the estimate if you want it done by them.
