I drive a 1997 m3.
Im debating between
CAI
Chip
UUC EVO3......
I can not decide.
Help with people that have experiance.
Pros to UUC evo3: All feel it everyday, not just when im pushing it
Cons to UUC evo3: No power increase at all.

Pros to CAI: all here it, and get 5-7hp lil more pep.
cons: I here it makes the OBD11 more of a bitch to work with sending out codes right and left
Pros to Chip:be able to go faster than 142 which I cut off at last weekend.
