Hello, I just purchased my 1st Mustang, a 2001 Cobra Conv. I called a recommended shop in Maryland to get a price for a 3.73 installation. I was told that to change to 3.73, a new chip must also be purchased for the speedo change. Has anyone ever heard of this? Need some help, new to this.

The shop I spoke with told me the only thing I could do was get the chip, I asked if there was anything else to use to calibrate the speedo, but they said no. The price to do this is now rising another $300, plus the price f the 3.73 change. We are talking close to $1000 total!!! I was also going to add a K&N, Steeda shifter and pully's, and possibly Bassani x pipes, but now I have to make some choices, can't afford all.
