Dump or bov,s

ok so have driven my meg home and it’s got a dump valve, I no what they do, which is to release excess boost pressure when the throttle is closed to prevent turbine stall.
Now I’ve never had one before and think I’m too old for one now but before I remove it and chuck it at the nearest chav is there a good reason to keep it really?
It starts to hiss when I get on the throttle about two thousand revs then dumps as I close the throttle at 2500. Which in sixth is about 80 mph so happens a lot.lol.
I get it’s use so is there an alternative or does it need to be there as it’s been mapped to 300 pit ponies. Sorry for long drawn out story but fuck all on tv
 
Standard turbo has a recirc valve so a dump valve is only for show.
 
I have a Forge recirc valve which sounds good. I didn’t fancy a dump valve because of my age!
 
The recirc dumps boost into the airtake.
dump valve dumps it into the atmosphere and can lead to turbo lag.
