Just wondering if anyone has heard of or even tried the airbox mod that Hauck has out. Not entirely sure what it consists of, other than K&N pods & PL box. I think they have a pipe mod as well, but I won't be going with that. I'm hearing numbers of 10-14 possible HP increase!!!! I know that most places give numbers that are rarely acheivable, but who knows. I know a dealer that has installed one already & the customer said it really seemed to improve the sled.
