i am by no means a guru or anythingat best im a newbie...i had this same question and thought i could make mine better as well. my stock is at a 91-94 at all times....i switched and it went to a 81-83...couldnt tell a difference on my end, but lower numbers are usually a bad thing. if you are coming from a older radio, most people do see a difference with a updated one. i would check which one you have,try it, and if its worse, you can always change it back...very carefully...
