Speedo Recalibration?

[97samssnake]

I drive a 97 Cobra with 410's. Is the gear ratio going to affect my speedo much? And how would i fix my speedo, it keeps going all over the place.

Yes, for 4.10's you can get away with a speedo gear.

for 4.10's you'll want the white 23 tooth speedo gear. This will get ya about as close as you'll get....it'll still be off a tad.

I didn't think a tuner would correct the speedo on our cars :shrug: ???

WIth my 4.10's my speedo is off by about 12 mph with the speedo gear. Only reason I can find is the previous owner put 255 tires which will change this week. I'll probably buy a speedcal soon.
