Thanks, Mike. Yes, I was on the bankspower website a couple of days ago and read that article (very informative), and I talked to someone at their facility in Azusa about installing a Banks system sometime later this year when I'm down that direction.

Thanks for all the information. MH is at the dealer right now so I am guessing on the redline....I think the bottom end of the redline is in the 1200-1300 range. So perhaps mine is pretty much normal.

Good question, and I don't know the answer to that just yet. From what I've read, I understand there can be a significant difference in the readings depending on the location. I'll try to get that info. Is there a way to tell with a visual inspection?

I have a new (to me) Itasca Horizon with a 300 hp turbo charged Cummins ISB 5.9L diesel pusher. The pyrometer readings are consistently at the high end of the "normal" range (about 1000 degrees), with fairly frequent rise into the "yellow" range between 1100 and 1200 when climbing and without towing. Perhaps some of you Horizon owners can share your expertise with me regarding safe EGT range for this particular engine? I know high EGT can be the result of restricted air flow. I've been reading about the Banks Power Pack System and wonder if anyone recommends this modification, which is supposed to reduce EGT and increase fuel efficiency.
