Installing gauges - what should the gauges read for "good" and what is "bad"

[Dan_69GTX]

Gonna install gauges.



Now - what is normal for these gauges, what is the value when I should get concerned, and when to "shut down".



Exhaust temp (pre turbo)

boost pressure

trans temp (manual)

trans temp (auto)

Auto transmission temps

Koa man posted some numbers a while back and one of the members sent me the web site address for Mag-Hytec. This is from that site -



Temp vs transmision life



Degrees Miles

175 100,000

195 50,000

215 25,000

235 12,500

255 6250

275 3000

295 1500

315 750



Since these guys sell a product that is supposed to help keep transmission's cool, these numbers may be slanted a little. Even so, I've seen this type info in several areas and it always points toward the same end results -TROUBLE!! Keep the temps down, the lower the better.
