Raising idle in INPA for exhaust sound

I'm conisidering slightly raising my car's idle in INPA to make the exhaust slightly less tame. I have a Borla exhaust now and like the way it sounds but I love the way it sounds on start up. By raising the idle could I achieve that sound always? I'd only raise it up 200 rpms or so. Has anyone had any negatives come from raising the idle in INPA?
