All Things Mk5 > Performance Modifications
Seems I need some new mods to get a map
rich83:
So even though the OEM pump won't exceed 130bar and the OEM FPRV is rated at 130bar.... You think a 145bar FPRV will make a difference WITH AN OEM PUMP??
With an upgraded HPFP... Different story.
And I'm out......

No!!!! When did I say that?!
Of course you need an uprated pump to make use of an RS4 valve!
Are you reading things properly, Rich?
Bizarre.
Dan_FR:
Sometimes the OE valve cracks before 130 Bar..... and sometimes (at certain revs) the pump might be capable of more than 130 bar, and if this is requested by Niki in the mapping, then an RS4 valve will be beneficial. The RS4 valve is 136 bar from memory - not a lot of difference, but those extra few bar may be all that's needed
Revo stick to 130 Bar pressure (as does my Revo map) so there no benefit to us (me and Rich).
I'd reccomend an RS4 valve and uprated pump though. Transforms the midrange
AJP:
I get this, Dan. I just think Rich has completely got the wrong end of the stick with this. Which is unusual, as he always comes across as intelligent.
@Rich83 Please read the whole thread again.
I had a Stage 2 R-Tech map. Got fuel cuts. Took it to Statller. Confirmed through logging that actual was well short of requested. Then upgraded the pump to a Loba. At this point, Steve advised me that the RS4 valve would be of further benefit. Which is what I've been saying all along.
It's clear that some 'Stage 2' maps request more than the 130 bar the oem pump can produce. And again, use of inverted commas is intentional.
You get me blud?!

I have an Ed30 with BCS prestige system with sports cat and Revo Induction.... Just messaged R-Tech and apparently I will need to go Stage 2 and bypass Stage 1...
which is cool, but now I need to source an RS4 valve (seen some at awesome so will get one from them) and a front mounted intercooler..
Anyone know whats a good front mounted intercooler to go for? I don't want to pay through the nose though as didn't realise I couldn't go Stage 1 so this is extra cost I didn't account for.
cheers for any help and links

AFAIK and as listed on R-Techs website the RS4 valve is not required on an ED30 until the the HPFP has been replaced and then it would be Stage 2+.
Hardware Combination of tuning level options K04 TFSI:
Stage 1 = Any hardware upgrade as long as cats stay stock
Stage 1+= Stock car with just cats removed HPFP & air filter upgrade
Stage 2 = Intercooler – induction kit – full performance exhaust
Stage 2+= HPFP – intercooler – induction kit – full performance exhaust – RS4 pressure valve
Stage 3 = Stage2+ hardware upgrades with Loba TTE or BBT K04 Hybrid turbo upgrades with a 155bar pressure valve and water meth injection.
