6637 question
Installed the 6637. Saw a small power increase, or so it seemed. Don't notice much change in the way it sounds while cruising but......
I am hearing a big woosh when the rpms go down after a gear change. The harder I am stomping on it the louder it seems. Is this the normal turbo sound that people talk about with this mod?
Also, noticed that the air intake tube of the old stock air box still opens up right next to the battery. This should be enough outside air coming in shouldn't it?
Thanks,
Steve

The whoosh (the Dart Vader sound) is very normal. The position of the filter is as good as it gets, it will get plenty of air. Time to do the ZooDad mod, which will bring in even more air.
