Hi Everyone,
My apologies if this has been covered before but, I can't seem to find the answers I need on other threads.
I have a 2012 Fat Boy which has the active exhaust valve & intake.
When I bought the bike from the original owner, it came with a Diag 4 Tune USB dongle, in an envelope marked "stage one tune" I have paperwork from Sycamore H-D listing a Stage one filter, along with the Diag 4 tune & an Eliminator kit (VH31001) the valve on the exhaust pipe is Permanently open & from what I can tell, the wiring to the actuator motor, is disconnected with a "bung" in place which, I assume is what the Eliminator kit on the invoice is??
Does all of this point to & confirm a stage one tune?
If I have understood things correctly, there should also be a "bung" somewhere on the air intake but, I'm not sure where I should be looking, is it an obviously visible piece? Or do I need to remove the cover to check it's there?
I'm asking all of this as I want to swap the stock headers & the V&H slip-ons that are currently fitted, for a set of V&H big shots.
I am trying to figure out, if the Diag4 tune that is on the bike, will be okay to run the big shots or, do I need to re-tune the bike??
I've tried my local H-D dealer but, they were no help at all so, I thought I would ask you guys...
I've added a couple of pictures, in the hope it helps someone answer the questions.
Thanks in advance for any possible advice.
