Your EGT sensors are broken

Default Nope. All EGT sensors only read from 945°C to 1035°C

Most cars won't show any EGT activity.

Default very nice Dave... Seems MTM has some throttle cut after max boost spike...

not what I would have expected for the car running the least boost overall.

Default if i read the first graph right, DAP you and MarkPs boost curves are the best match.

very little over shoot, and quick settling time. which means each car was running very well imho.

(this is from a control systems perspective)

Looks as though it would do well with an MBC in parallel to limit the initial boost spike.

No joke, 22psi cut back to 16, then up to 19, then taper to 16. That's a crazy rollercoaster

Default well, it's more involved...

There are other parameters involved. It's not just merely one trying to meet the other, unfortunately. One could tune a car and have actual boost right where they want it, but the "desired boost" may show different values entirely. I think some such tunes have been posted over the years.

Why's Mark's air flow so much higher than the others (330g/s)? Was he running the ram air?
