I'd say let the shop build you one, dyno before and after (covering all variables) (dyno dynamics if possible) post the results pics and video, invite other members in your area for witness, do some real road testing if possible and on a safe conditions, against another e39 M5 with mods...this will be a long process but if your up for the task, i'd say do it...
Mods: 91 octane with occasional 100 octane

" Despite its supercar attributes, the M5 still doubles as a soberly practical, spacious saloon - only with the ability to scare four passengers in comfort all the way to the local coronary unit". Top Gear
