If you have no intention of getting a remap, get a hybrid one. These are adjustable between full recirc or full atmos and anything inbetween. So you can vent some air to get the noise, and recirc enough to keep your engine happy.

I ran this one for a while before eventually getting remap, had it mostly vent but a small amount recirc to prevent lumpy gear changes.
