    No pics, but I did finally mount the PSC power steering pump. What an unnecessarily pain in the ass job, lol. Truck steers awesome and the brakes are better too. I was going to add a cooler, but time wasn’t allowing today. On a positive note, my father came down to visit (my bday is soon)...

    I’ll share my excel formulas and spreadsheet. I’m also going to get more sample data and let it eat in another gear higher too :). Tomorrow is power steering pump first though. Damned leaves today!

    I just found a thread on a forum that mapped our LB7 turbo and it's nothing like the one I saw here. It makes things make a lot more sense. I still can't upload here, so Post 28 link: https://www.rs25.com/threads/ihi-turbo-identification-and-compressor-map-help.198104/page-2 Now I can see...

    and I just realized that the IHI idea at the end is BS. Max effort at 31psi is like 500hp and that's more like 2x the lb/min I guesstimated. It's so far off the IHI map that it threw me for a loop and I don't know WTF to think now. LOL

    My ihi P/R rises to 1.88 (1.62 on the s475 at that point), and then as the wastegate opens it drops. I show that as 12.76lbs of boost. At the highest boost I’ve logged (51.587), I was 1.43 p/r on the ihi and 3.15 on the s475. I get what you’re saying about sharing the load “better” , but...

    That was one of my (many) initial stumbling blocks :) I'm interested in your setup where you defeated the wastegate. I'm seeing how that could actually be a great idea. I am concerned though about how much EGT I'm seeing as I tighten the wastegate though.

    I don’t think you can just add them to come up to total boost, since the secondary isn’t breathing at 14.7.

    Gauge needle repositioning

    Cool! Thanks, and “Bone-appa-titty” with your new three prong fork, lol.

    Gauge needle repositioning

    My OEM coolant temp needle is way off, but the pid reads correctly. Can I pull the needle off the gauge and re-clock, or is it keyed to fit the shaft in only one position? Thanks in advance! Wally

    I tried to upload the excel file as a zip file, and I keep getting an error: "A server error occurred. Please try again later.". It's been like this for a couple days with pictures too... did James get DEF in the server???? @Chevy1925

    I'm a little over a year older and maybe a little smarter about how this works now, LOL. My calculations were also off a little too. I went back to Idaho Rob's posts and I'm back playing with it tonight, and I found some interesting things. I increased the wastegate tension a couple times...

    Yes, Lucille is the sweet one that I found first. Not the huge Rottweiler I found the week after.
