which dump valve is best for tfsi rev g. rev d or aftermarket

[robokid]

Hi iv got a 07 cupra tfsi its running 360 bhp but i want to take it too 400 but i have a rev g dv fitted and i think its gone but which is the best one for the engine and the power
The rev g and rev d have different reviews but there is also another option which is the gfb dv+ which does have good reviews but bolts of to standard dv but if mine has gone ill still need to buy either rev g or rev d dv so which option is best price does not matter and the gfb dv+ says its stronger
All help is much appreciated thanks

Do a search. It's been discussed a million times.

From what I have read on the past. Aftermarkets are a bad idea. Rev D can distort in some way and leak. Rev G will eventually fail and need replacing. I have a Rev D on my FR but will probably look at a Rev G at some point down the line

To be honest either one will be fine. People recommend both D and G and they will both fail at some point like the rest of them anyway. It won't break that quick so i wouldn't worry about it so much. I've got the Rev D with no issues here.
