ISX 450 Intermittent Mystery Derate

[Allaroundag]

Haha - Just like me to be a couple decades behind the times! And here I thought I was moving up in the world from my 3406B and '83 KW and also doing right by taking a step back 10 years into pre-emissions from my ISX! I do get your point about the VG turbos though... Those things were certainly game changers.

Oh well...

I'll look for that ECI folder. I certainly appreciate the help as always!
