before, you know the temperature going into the turbo... after the turbo you know how hot your exhaust pipes are. You need pyro to watch the temperature of the exhaust running through the turbo so... put it before.

After?

So you know what caused your motor to blow when you run 1300* POST turbo rather then pre-turbo.

There is NOT ONE SINGLE reason to run a pyro post turbo.

And FYI, your not watching egt's for the turbo, the turbo can see temps in excess of 2000* for 30 minutes without damage...

Your pistons will melt at over 1400* for 2 minutes.

Pre-Turbo gives a more accurate temp of what the cylnders are at. The gauge will be alot more alive and move more due to the temp changes. And you'll see hotter temps However should that probe failed (ive seen it happen), you get to replace your turbo too.

Post-Turbo the gauge will act more lazy and be slower to react due to the turbo taking some of the heat. For that reason your temp will be lower. Every semi-truck on the road that has a pyro will be Post-Turbo.

Both ways are accptable, as long as you know what your looking at. I do know that 1100* is absolute max you would ever want to see after the turbo. After that the turbo fins will glow and warp. I personal have mine after the turbo, and that is the only way I'll do it, unless I put one in each manifold.
