I'm a newb to the Stock twins. I have an Aristo (real aristo) (gs300 with 2jz-gte from japan)
Anyways, I can't figure it out but my second twin doesn't come on all the time it's almost like it's not comming on at all and when it's supposed to come on the boost drops like crazy and the car feels like a snail and then all of a sudden the second twin comes on..
Any ideas guys? Could the valve be stuck that is supposed to spool the 2nd twin?
thanks kaiser... I think it's gotta be a line spit it's for sure not a borken turbo as it does come on.... if i part throttle it and give it good load it seems to come on (but very slow almost like it doesn't want to) I think that the vac line isn't getting enough presusre to push the valve open properly or somethign.
