[F]Rank 9 Federation Implant bugged?

See title. I got this implant yesterday - it claims to increase maximum afterburner speed by 20%, but I still have the very same max speeds as I did before. Does this work properly for anyone?

Nevermind, figured it out. I always thought the implants were grouped in Tiers, so a Tier 3 implant would work for any T3 ship, turns out they only work if it’s a ship that needed at least the same rank as the implant did. The mentioned Rank 9 implant works with the Rank 9 Wolf-M, but not with the Rank 8 Wolf MK II.
