just wondering what the exhaust temp should roughly be on my 3sgte. performance parts include 3" turbo back exhaust, rebuilt ct26 with larger compressor wheel, blaster 2 coil, nology hotwires and nology silver spark plugs D4YS, and a front mount intercooler. i have an exhaust temp sensor set into the stock exhaust manifold for the 4th cylinder since it was the closest to the motor. just wondering so i will be able to tell if my engine is running rich or lean due to higher or lower exhaust temps.

you should see 900-1000F at hot idle
you should see 1350-1400F when cruising
you should see 1300-1350F when boosting
you should never see more than 1500-1600F
