    As far as gears...everyone has their own opinion...best best is to try it out and go from there...you're going to get a mixed bag of reviews and a ton of opinions on what each person personally likes...

      Can anybody share the source information on where they verified that the BMW rocker arm PN 11-33-7-549-034 are DLC coated?

        My data point: 288/280 Cat Cams with new followers (oil bridge and E39 M5 pressure relief valves), Turner CSL airbox, Euro headers, stock section 2, El Diablo muffler, Alpha-N dyno tune by HTE. The dyno run before mods yielded 292whp. After mods and multiple runs, it peaked at 346whp so gain of 54hp. I just swapped to a more free flowing race muffler. I'm going to dyno the car again to see if it did anything.

          Would it be possible to post a dyno?

            Would love to know this as well. It’s looking like I need to replace the head gasket so thinking of changing cams “while we’re in there”. The Schrick rocker arms seem to be on back order, so would be great if these were a good alternative….

              The only source I can find is the website below. However, it's hard to tell if this guys claims are backed by a truthful source. I can't find much more info the P54 engine.

                  Thanks for chiming in! Just wondering how you found out these parts are DLC coated? Google doesn't come up with any info on the P54 engine details. I know several owners have used them without issue.
