I have a 2005 BA MKII manual T...

What is the most RWKW someone has managed to get on stock valve springs???

Would be keen to know.

And what other mods did you have?

you should get around 270 with injectors, but they are all different. I'd get the springs done now, that way you don't have to go for a re-tune

Also, if you relieve back pressure via a bigger CAT/new exhaust, you will be able to get a little more out of it.

Ive seen 340wkws from a customer car... BAmk1, auto, one of my cooler & intake kits and dump back exhaust, runs mid 11s.

But yeah, doing the valve springs is a good move

ive run 346rwkw on tunehouses dyno, with standard BA MK2 valve springs (highest reading on CV's dyno is 330rwkw)

running a process west intercooler and a dead cat + stock exhaust,

saying that I have been getting some valve float lately, so as soon as I get the funds they are getting pulled out for some stronger ones

I managad 322 but had to back it off abit as the valve float was an issue....

That was with the stock cat in place. Only mods are cooler, intake & injectors.
