I'm going to start shifting at 2100rpm now. Their range gave me 2100-2600 (previously shifted normally at 2400-2900).

PS - Sean, I assume you got 2300rpm for 1200fpm and 2900rpm for 1500fpm? The BWM recommendation is to upshift when you reach 1200-1500rpm, and we'd probably work on the low side, so you would probably upshift at 2300rpm.

Another factor is how far apart your gears are. BWM likely has internal consistency, but other makes are probably quite different; this would cause a different upshift recommendation (what, exactly, I don't know).

Edit: To me it felt like I was lugging the engine excessively shifting at 2100rpm keeping LOD at 75-ish. I'm going to try to keep it lower than I have before though, perhaps 2400rpm.
