Default Stage1 - remap or not??

Always thought that stage1 - changing both A/C and Exhaust required remapping. Is the statement below only true for Screamin Eagle components?

Harley-Davidson did publish some interesting power improvement percentages in the Fall 2006 issue of its Enthusiast newsletter. From the information listed below it must be assumed that you can upgrade the exhaust system and intake system on your 96CID engine without any changes to the ECU. Nightrider has historically been a proponent of exhaust system only upgrades with no EFI remap, but now HD has published that HD/SE exhaust upgrades and no EFI upgrades can be added to your bike without warranty implications. The table below summarizes power improvements as published by Harley-Davidson.

I wouldn't do a stage 1 without remapping with at least the HD download.

Never assume. Also, HD recommends the Stage I ECM download to create a complete Stage I A/C & Exhaust package. I would not recommend upgrading you Air Cleaner without some sort of remap.
