Anyone who has installed a Staintune exhaust in a f.i. bike : How much did it affect your f.i. ? That is, did you need a remap afterward or was it pretty much fine out of the box? There's a Staintune slip-on set coming in the next day or so for my 02' DL1000 and noone in that group has dealt with this combination yet. BMW guys/gals might come closest on this one. (big displacement, twin cylinder f.i. bike) Any input would be appreciated. Thanks!
