After installing the Vance & Hines 3" Slip on Twin Slash Mufflers on my 2016 883 Iron I found one map for their muffler but as all their maps just assume you have upgraded to a Stage I high flow air system . I plan on just keeping my factory air cleaner system . If I use that map will my bike then run to rich ? I have e-mailed V&H three times with no response . Near impossible to reach their tech support by phone . Thanks

Reason: added content
I can't say what the VE difference is in the V&H tune you have compared to stock.
The HD Stage 1 tune for exhaust and air cleaner averages less than 2% VE difference from stock from 1000 to 6000 rpms.
At full throttle the Rear VE averages about 5% higher in the stage 1 tune, the front VE about 1%.

Reason: speeling
You should find a map for stock HD air cleaner. That is what I applied to my bike before changing the air cleaner.
It made a marked difference and removed the lean running raspy note from the exhaust.
