It has a modified 950 Dominator on it. The problem with using EGT for cylinder balance is that the thermocouples don't all read the same. Also, they are super sensitive to placement. So as far as I'm concerned, if they are within 100 degrees then they are equal. If you wiggle the thermocouple around you can change the temp quite a bit so that tells me that the thermocouple placement is changing the reading, not the mixture.

Here is a video of a dyno pull. You can watch the EGT readings if you want but I don't pay a huge amount of attention to them.
