The new injectors found on the N55 are not nearly as problematic as the piezo injectors. Open-deck blocks and cast pistons are not great at handling extreme boost pressures for long periods of time. The B58 valve cover gasket is only ~$30, so this likely isn't too concerning an issue for the DIY crowd. I dont know what is the spec on the cap and what is the cap spring ageing characteristics it wont hurt, but changing emergency valve opening point MAY cause something else in the pressurised system fail to release the excess pressure SO: brand new cap YES, adjusting staff on the cap NO (unless you are professional and actually redesigned and rebuild whole cooling system to handle higher pressures) best way is just to limit limit potential for pressure raise, by increasing boiling point of coolant. Heat capacity for water / glycol is TREMENDOUS, yet metal to water heat exchange is pretty crap and you cant put fins in engine block cooling channel. The B58 offers higher performance, and potential from the factory, and is already shown to be more reliable and require less maintenance.
