hey guys heres my problem... my setup is an b18b1, turbonetics turbo, external turbonetics evo wastegate, vortex bov, golden eagle vacum mani,fmic, 450 dsm's at 9psi..now it runs great and im happy with the track times but if im cruisin' on the highway and im not in boost when i hit the throttle it sounds like my wastegate starts fluttering and the boost gauge starts jumpin all over the place????? and the wastegate is fairly new and so is the bov..ive been playing with the bov adjustment but it doesnt seem to be making much of a difference..... the turbo has the vaccum fitting on it soo i hooked the wastegate straight to the turbo and the bov to the vaccum mani... idk what to doo!!! im thinking either the wastegate is no good or the turbo is no good but it preforms great when i abuse it..... any suggestions or advice is greatly appriciated

Fluttering is one thing, but does it just flutter all the way to redline or does it flutter for a second or two and then go into full boost.

If it does the latter, your turbo is hitting the surge point.

is all you piping conected. once my intercooler piping came lose and you can hear it sucking but dont hold boost i bet thats what it is

the boost gauge only jumps for a second or two then hits full boost...... what can i do to prevent it from hitting its surge point? is it something to worry about?

ive heard running your wastegate open with no dumptube can cause a flutter when crossing over into boost?
im probobly completly wrong in this case though.
