if i get an EGT gauge what temp shows the car running rich and what temp shows it running lean? I just don't really get how to read it thanx

Are you Boosted ??

It really all depends on where you have the EGT Sensor along your exhaust...Right out of the manifold will show hotter then down by the Y-pipe split.

The best way, if your boosted, is to get the EGT guage, get Tuned, then run a few full boost runs and record your temps...then down the road, you know what a good reading is

If your not boosted or spraying, there really isnt a use for an EGT gauge...your not adding any more fuel or Air

i am boosted, and i'm a month away from going to a tuning shop... but i want to know if i am running lean or rich or wat not... it would be mounted on the Y pipe so what is a good temp for a boosted car w/ a 3.125 pulley?

What FMU are you using, if any ??

I am currently running a Cartech FMU, Walbro pump, AEM FPR, and I have the EGT mounted right where the Y-pipe Comes together at the Y...I see anywhere from 1200-1300 full boost...which may be rich cause I have it set up that way till I put in my JWT..I will see what is normal when I put in my JWT, 370's and MAF
