ok, so i just picked up my car from the shop...i had 3.73s w/t-lok installed and i'm breaking them in before i race 'em. now i just need to recalibrate my speedo but what would be best: to get a new speedo gear or just get a chip? thanks for the help!
well if its a 99 up manual buy a dallas speedcal from dallasmustangs.com i have had one for over a year maybe nearly 2 and its been great, it is said to work on autos but not sure so ask them first. if not you will need a chip. for pre 99 you can only pop in a 23 tooth speedo gear and it still wont be right, if its a manual you can pop off the tial shaft and put a diff drive gear to match with teh speedo gear you choose and get a correct reading but not sure which gears you want to get.
is it an auto or manual? not sure if it works for autos.... or pre 96s at least. its not hard to hook up pretty quick actually but i would not use the connector they offer for the all time power it kept comming lose on my car just use a sodering iron or something better than the little snap no connector they provide.
i have a manual and yes it will work for my '94 according to mike from dallas mustang. i asked him twice to make sure that it would work and he said "yes it would restore the speedo to 100%." the speedcal should arrive on saturday.
