Not trying to be rude, but maybe you should get your facts straight and/or check with your father about the speed governor. I find it difficult to believe that BMW would have a "secret" speed governor 'release'
in P500 ///M mode.
And, if you didn't remove it and if your father didn't remove it, then guess what? It's governed at 155mph.
I believe you hung in there with an E60 M5 for at least until say 100-120mph (maybe up to 140mph), but based on your recent comments, I do not believe you in regards to your claimed HP of ~ 430HP (especially w/o PROcede v2.0) and the speed governor removal thing.
I do think ~430BHP (not 430WHP) is absolutely possible with the mods you've listed + PROcede v2.0, running on 93 octane though.
I just don't think you're there just yet (with PROcede v1.4x, DPs, exhaust, FMIC, and Methanol).
