So I picked up one of these.....
Have heard some good and bad feedback about this product but it would seem the Bad feedback is mostly to do with the earlier versions and even some dodgy Chinese copies floating about.
A few people running them on stage 2+ and hybrid had said that there is a noticeable difference in how the boost is held ect compared to the stock DV
The DV+ isn't going on yet as doubt I would notice any difference but they always say every little helps....
