    Interesting story. Do you have any plots of your setup at 16psi, like boost vs rpm and AFR vs rpm?
    I see some logs on post #462. There may be some others in the thread somewhere but not sure. I could use a refinement on the tune to get some more power but the car runs just great as it is and I use it as my daily driver. I'm not motivated to get into the tune again (for now). What are you working on?

    It's great to see you still developing the SC setup on the M62. Im still playing with it albeit with an m60b40 in e34. It's been pretty reliable of late but its in the shop now awaiting the long overdue custom header installation, and standalone ecu. Having to also upgrade the clutch for a 2nd time as test fitting and driving with the headers made it feel very strong and had clutch slip. Headers are getting ceramic coated and I'm going to play with the exhaust cam timing. She made a healthy but header restricted 450rwhp on e85 @ 16psi. Im thinking its going to move into the 500's once all is done. Then that will be it.........no more developments or upgrading LOL. Im moving into my mid 50's so its probaby too much car for me now.

    Anyways, nice to hear you’re making a butt load of RWHP.

    I’ll drink to that!

    I’ve got another 30K to go before I get there.

    Thanks Jim and Nate. I’m just really happy that the used piston I put in is solid. Oil consumption is almost nil. Super stoked.

    Jim your 540 is not getting much road time. We were close in mileage a few years back iirc. Get the old girl on the road!!

    Chris, that is fantastic!
    Even though I know I'd loose to your old girl, but my new mistress with S85 would give her run for her money.
    It's comparing apples to oranges but this V10 screaming at high rpm is something else.
    Congrats again on that awesome milestone!
