EXHAUST TEMPS probe in diff locations
Does anyone know what the differance on a pyro would be ( just cruz'in down the highway for eg) if the sender is in the exhaust manifold compared to in the down pipe.

Many factors involved but this has been discussed many times on here. Do a search on probe installation and you will see all the arguements. I have mine in the left (drivers side) exhaust manifold. I lost a turbo (no boost until 2400 RPM months ago. I took it in and the dealer replaced the turbo and never mentioned the location of the probe AT all. I have no reason to believe the probe location had ANYTHING to do with it but they could have said something if they wanted like "oh something broke loose from the probe and took it out". Most dealer don't really care. My dealer asked when I was going to "chip" it.

Whopper809,
I have done both to the same truck and loaded w/10,000 lbs and stepping on it pretty hard on purpose on a good incline I got over 600 degrees difference. Our company stance is is your going post turbo don't both installing it at all, it will just give you a false sense of safety, nothing else. The class 8 truck guys will say post turbo, but they have a pro driver and a multi speed tranny that they row to keep the truck in the right pulling gear, they also have a very small RPM band as compared to a 7.3 and much less a 6.0 redline at over 4000 RPM so that makes a ton of difference too.

Pyros are designed to be installed 4-6" from an exhaust valve. Anything else is wrong, for liability reasons they will tell you to install after the turbo. This is only because if the probe breaks and does turbo damage they would have been responcible.
