It was pretty evident to anyone with even a passing knowledge of the rules that the Boosted Reflexes rules for shadowrun 4 (from The Way Of The Samurai) was pretty rubbish. You were better off with a reaction enhancer or wired reflexes, both of which were ironically both cheaper and far better. No sane being ever took them for the crunch.
Now, with the new rules for initiative in 5th edition, boosted reflexes (as presented in TWOTS) are marginally less laughable.

Level 3 2.7 +3 +1D6 2R 47,000

Anyone willing to weigh in on whether this would be balanced?
