Gear Help!

I am going to be installing 3:90's and was wanting to know is a tune needed to fix the speedo or what is needed? I had 4:10's in my stang but the shop did it with everything else so I had no idea what they did. Forgot to ask. Please advise!

I don't think you need a TUNE.....You will need a hand held tuner or EFI LIVE, HP Tuners. Go to gear selection and type in the new settings....When you here a tune is needed, you don't want to go where you don't have to...
