I'm going to. A lot of tuners out there will preload the tuner with a tune based on your mods. After getting my car dynoed at Mustang Week, I ended up with 317/339 but the car was running extremely rich. With that being said, I want to get the A/F ratio down until I can get the car dynotuned. So I'm just going to have a tuner install a tune on the tuner before they ship it to me. Its free so why not?! I could just get one without anything preloaded on it just to fix the speedo and then adjust the A/F ratio on my own, but why not try to pick up a few ponies with the free tune
