Well, I'm gonna head over to my shop today, I'm gonna check the air filter/exhaust for restrictions, check/adjust my valve lash, and mess with my starwheel and AFC housing a little bit.

Someone suggested the AFC thing to me, and it made sense when he said it, but now that you mention, it makes sense that it wouldn't too.

the acf will make a difference when you hit the pedal but not at idle ... how was your valve lash?

I know that when I bought my EGT gauge it was matched to the thermocouple. I wonder if you have the right thermocouple to gauge setup. I know the vendor sent you another but how did you check to see if it was somewhat accurate. You could always bring some water to boil and put the thermocouple in the boiling water to see what the gauge reads should be 212. This is not for complete accuracy but should be close.

some one may have put something in each of your stacks, bot enough to keep it from running, but enough to cause restriction. just a sugestion. hope ya get it figured out. u didnt cut the excess off of the pyro line did you?

Unfortunately, didn't get to the valve lash today, a buddy conned me into doing his brakes so he could pass inspection. Gonna get to it tomorrow.

Relay93: Good idea on the boiling water thing, never thought of it. I'll have to give that a try too.

Stacks look clear, still blow out plenty of smoke. I also left the 100 extra feet of pyro probe wires intact.

Yep, you got it! Ok, maybe I was exaggerating a little.
