Hi Guys

just wondering if i can run just a needle valve to control spool rate of my turbo or do i also have to run a drawes valve as i don`t have any over boost problems and have a boost gauge to keep an eye on things.

I just want to have a nice linear boost curve that doesn`t bounce round all the time.

Have i got the right idea fitting the needle valve to fix this problem or am i barking up the wrong tree?

Guidance from Gurus please.:)
