The keyword is "claims."
DINAN claimed to bump me up 100+ hp on my 550, costed over $3k to install. Few months later, taken to the strip and the car is performing identical to stock. Gave them hell, they took it back in, "retuned it," and i don't think anything has changed.
Bought a BMS S1, within a few weeks it made all the difference. Now even in just Sport+, mashing the gas will cause the rears to spin a bit, it's worth it by a whole lot.
