Just installed a RokTech on the '05 today at the shop; it seems as though the EGTs are higher when fueling, and get higher more quickly... would advancing the timing cause this, since the engine is more efficient now?

 

I have no idea but would like to know myself.

 

Should be the opposite, lower EGTs with more timing. At least mine did.

Make sure you rotate the sensor in the correct direction.

But it only goes in one direction (up)... and I advanced it all the way.

 

What's the before and after EGTs?

Mine dropped by about 100 degrees.

I only drove it 25 miles back from the shop so far, but it seemed like it would reach 1000 -1100 degrees more readily than before, with normal driving. I tried a couple of WOT runs and it didn't make a noticeable difference in EGTs - just seems like the gauge is more sensitive to throttle pressure now... maybe I was just hyper-sensitive - you know how it is when you've just tweaked your rig!

No way I'll be venturing out in this mess today for testing...
