Actually from what I have read its needed to get past 47. But no it's not terrible as the engineer said it will reduce life but it won't e noticeable. Maybe you loose 1 year off of the 25 year life of this chip. If you don't upgrade in 24 years there are bigger issues at hand.
Edit: my chip boots 49 without it enabled.
