Tbh Andrew, maybe be different on the larger turbo, but after installing my revo one i actually lost about 10bhp as the ecu was complaining about too much air...
Unremapped gains for the exhaust was 20bhp. And, admittedly mapped gains so unknown what they would be if unmapped, of the wagner fmic was again 20bhp. Its unlikely that a intake would develop that, but who is really going to get an intake and not a map honestly
