but u dont have a turbo? therfore making exhaust temp even more useless than it already is...
its even fairly useless for a turbo engine (or race engine)
but even with a turbo car, they are meant to tell u if ur turbo is getting too hot or something is fked and if ur going to start/or have already destroyed *poo* in ur engine
and alos possibly if its too cold to thrash
but to be honest i think if ur just having it for lolz u could get a more lul-ful gauge, like an AFR atleast that'l move with engine load and throttle etc
