ROH ECHT:
So you ED 30 people do have to upgrade your hpfp as well as opting to add the RS4 valve, correct?
Sorry, I began thinking that you didn't because there wasn't any mention of it being done really or being posted in sig - mods.

So then why do they have different versions for the S3, ED 30, and Cupra? I had heard that the difference was a slightly larger fuel lobe, but this is turning out to be incorrect info, yes?

What difference did it actually make if you don't mind me asking? I was told is wasn't worth bothering with :stupid:
--- End quote ---
there is a difference in the valves on the gti, some allow 124 psi others up to 135 psi, it's a gamble whether yours allows the extra pressure of an uprated hpfp to stay or releases it, and at the same time the low fuel pressure also drops. so a mod worth doing IMO :happy2:
ROH ECHT:
So which RS4 valve should I get - B7?
