dumpvalvless
got a classic and fitted a fmic , so needed to buy another dv. got an hks one second hand and the car juddered really badly on lifting off from light throttle, also had idle issues,
anyone recommended tome buy a forge unit as it has different spring rates availabel, ended up buying turbosmart as its adjustable and it idles much better and almost totlally got rid of the judder on light throttle
any whilst being mapped i was told id probably need to just ditch the dv altogether, i think some cars/setups just dont get on with them, and as my car runs a tdo5 should be able to cope
so removed it and it is still slightly doing it? any ideas?
its a 94 sti, with
fmic, walbro, apexi power fc, apexi avcr, blitz turbo back exhaust
also it actually sounds like the dump valve is still on the car lol

Sorry mate couldn't resist 
Seriously, I think your post illustrates PERFECTLY why OEM ones should just be left on i.e. the engine is designed to work 'properly' with the OEM one fitted.
Prob not the answer you want... but I'm convinced it's the best answer....
