Anybody have a good source for springs.
mine has yellow which should be 0.8-1.1 but is nearer 1.1 all the time
id like a 0.7-0.8 for a lower boost tune.
hks only list 2 officially
thanks

 

It sounds like you've got your preload adjustment cranked all the way to maximum, hence why the 0.8 spring is at the top of it's range.
Make sure your preload screw is all the way out.

Wastegate springs are precisely manufactured and tested to achieve certain boost levels. I would recommend sticking with factory springs.

 

thanks for the reply,the pre tension bolt is completely wound out,
its on its lowest presssure.

i know just want to lower boost for tuning

 

If it's wound completely out, the wastegate is either too small, or the diaphragm is leaking.
It shouldn't be giving you 1.1 bar of boost.

 

i did think it may have a spilt.im going to take it off and check it.
