Can I adjust the tire size ans the gear ratio with xcal2 ? I've a 98 GT 5spd
and from what I've read, I can't with predator but i can with xcal or a speedcal.

Should I buy this ? It's mainly for the tire size, gear ratio ( change to 3.73) and data logging.

Thanks

Hard to recommend whether or not you should buy it when we don't know your mods, though.

you cant adjust gear ratio with any hand held on a 98. 98's have mechanical speedometers The only options are a speedo gear or a speed-cal.

thanks for the reply.
For the mods, for now i've only a cold air intake . I've a zex dry kit + alot of accessories but i'lll probably trade it for pi heads/intake (someone interested?)
Is it true that speedo gears (little white gear) tend to not last very long ?

Unfortunately this is true. Speedcal would be the preferred way to go as it's more adjustable and you can more accurately correct the speedo. The plastic gear is also more apt to crack/break over the stock gear.
