Egt
Its highly likely the sensor isn't reading properly..
However, there is the possibility that you installed the cam angle sensor 180 degrees out of phase, that will confuse the ECU, i suppose its possible to get ignition happening at the wrong time, but since its a wasted spark system the car would still run. That could explain it, though I have never experienced what your describing before.
EGR Temps in the ECU are basically useless, its actually some modified value of the coolant temp used for the EGR Bypass functionality (cold start function basically) So it won't in any way look like an exhaust temp like EGT. (this is just a tip if your confused why the values aren't what you'd expect)

Can I as a layman check to see if they are lined up correctly or should i take it to another garage?
Before I installed the cams the EGT was just fine.

LAst night i did an evo scan log both in 3rd gear and 4th gear, knock was no more than 3 for less than a second.
I just saw that there is a hole right new to the egt sensor where the bung was welded, and air is escaping from the hole.
Would this cause the EGT temp to rise so high. Also I checked the timing at cam gears are spot on. Not sure about the crack.
