hey guys, i'm new here and although i've had my '98 gt for a little over two years it's basically stock except for dynomax race bullet mufflers. anyway's i'm going to have new gears installed real soon (and i'm gonna have them installed at rearend specialties in santa clara, ca so if anyone has info on these guys please share) and was wondering what was the best way for me to go about correcting my speedo. i don't see myself doing anything more than catted x-pipe, headers, and throttle body in the next year so a custom chip can wait. so other than that what should i go with, speedcal, speedo tooth, etc.?

I'm using a DM SpeedCal for now 'til I get a few more mods done over the Winter. Then I'll get my speedo corrected when I get a chip and dyno tune in the Spring. BTW No problems with the SpeedCal what so ever.

Diablo Predator!!!

Not only can you adjust the speedo for the gears, you can adjust a lot of other things with the car, and get some more horsepower out of it while you're at it.

I also got the DM speed cal but I'm in the process of swapping it for the predator. Should have gotten the predator in the first place. It's well worth it.

If you plan on using the stock tune with the Predator you won't be able to change the rear end ratio. It's a known problem that Diablo is trying to fix. Just some food for thought.
