as anyone any info on it good or bad how lowd is it thanks in advance alan

 

Just put one on MY98 wagon, its gr8 only slight response gains, but thats not wot its for, it will provide longer life to ur turbo as no stop start. Makes nice woosh which with all out foot to floor is pretty loud no matter wot anyone tells u. Down to personal taste really.

 

Bought a HKS SQV from TDI yesterday and the chap there said that dumpvalves shouldn't change the performance at all.
