About a year ago I came to the conclusion that I wanted to run an EGT along with my wideband for multiple reasons.
1) No matter where I search, I everyone runs a different AFR on E85. So how lean can we run it? It doesnt like to knock, so the next possible way to damage the engine is to melt it down. EGT gauges will help you to know where to stop leaning it.
2) Egt can help you dial in timing. Not enough timing can cause high EGT's because fuel is still burning as it passes the probe. While lower egt's, may equal not enough. While always watching AFR's
3) While pushing 150-300 hp per cylinder on these engines, they are being highly maxed out. Data is key, the more the better and if you can afford it, it can NEVER hurt to have more Data.
4)While AFR's may be correct, EGT's can still be high. Things heat soak, engines heat up while doing a pull.

Turbotalon1g: I'm with ya, it can never hurt to have that gauge. It WAS old skool, but I really think these will make a come back. Old skool also considered 400 hp insane, now we easily double that. A WB02 that cannot tell what fuel you are running is not as accurate as you think. While temperature is still temperature.
