Not sure if this is in the right spot, but anyways. I just got done installing a boost gauge, BD manifold and a pyrometer, autometer sport comps. After the install I drove it around and everything worked great. Went out to eat dinner and on the way home the egt shot up to 1100 and stayed there even when crusing. I pulled over and even at an idle the egts were 450. Could the gauge have gone bad or did it go into regen mode. No regen light or anything. Oh it's on a 2007 LMM. Thanks

first off, welcome to the site!

im not to sure on the temps during regen, but sometimes the probe will go bad.
what kind of gauges are they?

Autometer sport compII

Make sure you have a good ground. They are picky when it comes to the ground.

I double checked everything this am and the grounds and hots are good. Might have to send it back and get another gauge.:mad:
