If you want a flash - I would go with either Dinan or GIAC. GIAC just released their flash loader which should work with the 535 too - it allows you to switch between different maps.

yes, their hand held map switcher is available, however I do believe it switches from stock to GIAC flash only (eas has a thread in the vendor classified section regarding the loader and flash). As GIAC states their tune is invisible, the only reason for switching to a stock map is for when you go in for service and to not tip off your SA or tech that you have an aftermarket flash, since throttle response and gear switching is altered with the GIAC flash.
