hello! , im 100% fresh into chiptuning, starting out NO one in sweden can deliver a good 335/535D stage 2 remap without limping in high speed (boost deviation to high and limping) .

So im about to try fix this by myself, KESS v2 is on its way home. If there are someone with a really good, maxed out stage 2 remap for 535D lci 2009 pls tell me, i want to buy it. (mods: dpf off, egr off , swirl flaps off , xhp tranny tune)

one bonus question: Can i just buy a map, here on the forum for example and write it directly to my ECU with kess v2, or do i need to "remove" my old stage 2 map that i allready have in the ECU first?


Have a nice day!!
