Been running with a Forge twin dv for some time, and still find the sound amusing on the old volv, but have heard about problems of running rich, can this cause the car to stutter? normally at low rpm.
Will a hks ssqv with recirculating fitting make a noise?
Dont really want to lose bov sound, but if its causing probs, its gonna have to go.anyone else experienced problems with bov causing stutter or hesitation?
Gonna get new plugs just to rule that out, its had recent leads dizzy cap and rotor arm,

Is it a t5 you have ive just been doing some reaserch on the dvoo4 twin piston ones we have as my car only seems to have a very short dump causing turbo chatter through the cone filter i also find that if i boot it through 1st 2nd then go into 3rd it strugles to build full boost but if im just in 3rd theres no problem building boost.
Any way ive just got a reply from forge and the standard spring in them is a blue on which is for 23-30 psi which is too strong for our cars and wee need the yellow one allowing 15-23psi as im running 16+ psi if yours is stock and running at 9.5 you will need the green spring rated at 5-15psi.
Im going to buy a kit there around £20 for 4 different springs if u need the green one and me the yellow ill split the kit with you for half the price.
cheers pete
