...my probe is right after the downpipe but before O2 sensor? Keep in mind I need the corrected temperature because Right now it doesnt go higher than 1000-1100F.

 

move the probe, it should be on the #3 cylinder and the distance from the head should be half the diameter of the pipe(for example, if the primary off the head is 1.5" then the probe would be .75" from the head)

should hve the probe before the turbo

 

there is no way for someone to guess what the corrected value is. it could be anywhere from 100-500 degrees, depending on exactly how far from the turbo. The way to use the egt, apparently, is to get your car dyno tuned and then if the egt's stay at those same levels; your car is still tuned properly. if they change; something is wrong.

Mine is in the 3rd runner on the manifold and I don't think it's ever gone over 1500 and rarely over 1400 with stock timing and running VERY rich. cruising is 900-1100, depending on rpm and load.
