I'd appreciate feedback about the following:
1) acceleration figures of the 991 turbo/S
2) temperature impact with stock inter coolers
3) reliability from owners who used it on previous 911 turbo generations
4) ability to be detected by the dealer
5) does need to stay plugged in? Or it can be removed after the install.

Thanks in advance.
