Turbo Sound Different To Stock

[RamR33]

Hey guy just have a quick question and need some help cause dont no wats wrong.

i purchased a hypergear PU turbo and installed all perfect no problems.

the problem im having is when i hit boost it just doesnt make any suction or turbo sound and if it does its really low and flutter or even my bov thats plumed back doest have the release sound and im hitting like 4 psi.

With my stock turbo i had before installed which is a S1 turbo it had suction turbo sound and flutter and release pressure of my bov and it was plumped.

i thought it might be the lag abit on it thats why it needs to hit more RPM but still nothing just a faint lil sound but my stock turbo sounded crazy .

ive got alloy intake pipe not the stock rubber one.

Any help would be great cause cant take it to hypergear a lil to far at the moment to get there so just thought id ask here if anyone had come across anything similar.

Big dirty boost leak ?

get it on a dyno, it won't work best until you get it tuned I reckon

check actuator preload.

Just getting checked now on dyno,was thinking big boost leak aswell.....had tryed the preload 2/3mm but still nothing last night still hit boost like 4 psi but not thrashing and that normal..,i checked everything in oil feed line which oil was coming out as ussually turbo spins freely and great and minimal shaftplay...has to be big boost leak for sure cant think of anything else.
