Hi i have a 48 sportster and i have fitted Rein Hart cross back race pipes and Arlen ness stage 2 air cleaner. I was told to get a sreamin eagle race tuner (sert) to suit this set up. had the the bikes 1600km service after fitting these parts and the dealer fitted the sert for me and now the bike runs real ruff like it has a fuel block down low. if you are riding at 60 in 3rd it misses farts and carries on but open it up and it pulls hard. so now the dealer is saying that i need to put in a screamin eagle pro tuner (sept) to iron this out because the sert only has set tunings and the pro tuner can be played with.  just would have liked to have been told to put the sept in and not the other piece of #*@! that i have waisted my money on. So dont buy the race tuner buy the pro tuner.
