EGTs too low?????

[Davison]

Probe installed post turbo, and now that the truck has 12K miles and is 10 months old, my egt's are lower and lower!! Power is up and mpg's are better too.



It runs at 300 around town and at idle goes down to 200 or below! Hardly ever have to wait for it to idle down to less than 300 degrees.



I was suspicious that maybe the unit or probe was wacky, but kept my eye on it when on hills and the temps went up to 4 and 5 hundred.



Anyone have any experience with this? Is all okay or is something funky?



Thanks

Do a WOT burst and see if your temps climb to 800 or 900 post turbo. If they do then all is well and wish I could get better mileage. It has been stated that if a person can keep EGT's low then MPG will increase. Sounds like that is what is happening to your truck.

check it!

Those EGT's sound very low



I would check the probe and gauge



But I am use to preturbo readings

Your post-turbo temps sound consistent with mine. The highst I've seen pre-turbo was around 1100* (stock, dirty, OEM air filter, empty, heavy right foot), and I was seeing about 850-900* pre-turbo then. I have an Amsoil air filter in now, and around town the post-turbo temps are much like yours.

The connections are loose somewhere, probably on the back of the guage itself. They require a good connection to read properly.

Readings sound right on-par with a factory truck with a post-turbo sensor. You'll lose 200-275 degrees with your probe installed post-turbo, so you should subtract that amount from any of the "pre-turbo" numbers you see as being normal.



My stock truck would hit 1050-1100 degrees pre-turbo on long uphill runs with my foot all the way on the pedal. cruising around town it was between 500-800 degrees.
