Default Temp Gauge Linearization?

Hey guys, I want to Linearize my temp gauge on my 97'.

I found this guide:

Monte - 1994-1997 MTGLP

Problem is I have a set of Rev Limiter Revolver gauge faces, so my minimum is 120*F, middle is 180*F and max is 250*F. The first range he shows has minimum of 120*F, but a middle of 200*F and a max of 270*F.

I tried emailing him asking for a custom range but the email failed to send as the "address doesn't exist".

Anyone know what I should do? Thanks.

UPDATE:

A bunch of people on other forums and a few friends of mine who have done the mod HIGHLY recommended against it. They said it works for about a month and then the resistors seem to overheat and the gauge just shakes and becomes useless.

So I got an OBD2 reader from amazon and the Torque Pro app. Pre-coolant flush she idled at 205, post-coolant change she idles at 195 and on the highway she fluctuates between 195-205. Now that I know she's healthy I have no reason to worry.
