if you find you are not the happiest with the map you download, or find it runs a bit rich its something i've seen from other 'downloaded' maps, they can be tweaked manually but its best if you do some research in the matter... I downloaded a couple different FULL EXHAUST maps which would match my new setup and found both of them had +10s written in the lower TPS % columns in lower RPMs, i ran with this setup while viewing my AFR with a POD300 display and found it ran pig rich off the line, auto-tune made suggestions and they were consistently removing the extra fuel so i zeroed out all the boxes which said +10 in the 5 and 10%TPS columns (at low rpm as rest on said columns were all zero), while changing the 2%tps column values to +5 and found the mix, as well as the bikes ride-ability improved greatly... running AUTO-TUNE is a great idea if you find your bike is running pig rich, and it should be evident by a strong smell of gasoline. Its something to be aware of as most will just keep swapping maps only to find they all contain similar extreme adjustments which are unnecessary. do a search on here for both auto-tune and pod 300 for more relevant information, i've posted just about everything i've learned from a couple tuners along with info passed on by Dynojet Research themselves :thumbup
