Wow, Big Difference

Ok for the past year and a half I have had my pyrometer probe installed in my down pipe and I have always known that the temp. reading was NOT accurate. Last week I installed my new 4" turbo back exhaust and decided not to put the pyro probe back into the new DP... so today I finally decided to install the pyro in the correct spot (in the manifold) and WHAT A DIFFERENCE IN TEMP I see on the gauge!!! The needle on the gauge moves up way faster now that the probe is in the right spot, and Im glad I can finally monitor my EGT's accurately so I dont hurt my rig.

For any of you guys out there that have the pyro probe in the DP, I suggest you move it, it makes a WORLD OF DIFFERENCE. The temps I was getting before I moved it were 300-400 degrese off!!! It may seem crazy to say that there is that much difference in temp in such a short distance but there is!

Move them probes to get an accurite reading and you'll be much better off.
The install job is super easy took 10 min. to do. Did not stress about the metal shavings like so many people worry about, all the shavings fall right down your sleeves and burn your arm not go into the pipe!

Just my 2 cents on EGT's and the pyrometer, in my opinion a very wise move to make if your running a downpipe mounted probe!

Even if the SMALL metal shavings get inside the pipe it's no big deal - it's only going through the exhaust side of the turbo.
