EGT readings lower at higher boost?
I have a Computech EGT gauge. It has a record feature that allows you record egt and rpms. At around 7psi my egt temps are around 1350 F at WOT. I switch the boost to 11psi and I notice that at higher boost the egt temps are lower, say around 1255 F. What would be the reason for that?
Also, the Computech gauge has an additional plug for a secondary probe. Would it be a good idead to tap it into my charge pipe (after the intercooler)to monitor the ambient temps going into the motor? Just to have a general idea of things.

Well from experiance,
Bump up(advance) the timing see if egt drops. Go to the point it doesn't drop anymore. From that point retard 1-1.5 degrees. If your egt drops way to much you are knocking. Also check your AF with 94 octance you want something like 12:1 or 11.7:1
I hope this helps. What are you cursing egt's?
