Default will new gears mess up speedo?

i've seen gear replacement kits that offer an included speedo correction computer, is this necessary? how much do new gears throw off your speedo?

The higher away from the original ratio the more it will be off.

As PRO50SC said it depends on the gear ratio. For the corrected speedometer gear see HERE

Ya it depends on what gears you buy but you can find a speedo gear for about 8$ but that may depend on where you live.

i'm not even sure where the speedo gear is located. is it easy to swap out? is it better than getting an expensive programmer? (i have a 95 GT)
