Hi everyone. I was lucky enough to pickup a flanged AMS licp and will be throwing on a TialQR since my Synapse Synchronic wasn't playing nice even with the aby.milspec spring. I did some research on the spring that comes with it and noticed is was -11. I'm pretty sure this is also the same spring type that ships with a brand new ams piece with the QR already on it. I've read that I should change to the -6 spring because of flutter/surge. I will be retuning immediately, but was wondering if I should stay with the -11 or just go with -6. Would AMS have already done the spring swap if it really needed to be changed?

 

Sup Bro!
im on AMS LICP with QR on 6psi Spring
already Tuned, No Fluttering!!
love my set-up!

 

Does it it make a high pitched whistling sound when you just press the gas very slightly?
Not the turbo whistling spool sound, but like a high pitched leak lol.

 

choose your spring pressure based on the vacuum at idle.. if you choose to stiff of a spring it will stay open and whistle like you just said above..



what vacuum are you producing at idle?

 

I have the same bov, mine came with a -11psi spring but i installed a -8psi which was still abit to stiff so i went to a -6psi spring and works perfect. Here is a video with the 8psi spring. The first video around the 4:38 mark (during one of the turns) you can hear it flutter.

 

Hmmm. You and Wraith seem to be on the same page.
It does say to chose by vacuum though >_<

Your 2nd video is 8spring as well? Sounds good.

 

Wraith went with 6psi right off the bat. I decided to try the 8psi but after a few weeks i switched to the 6psi spring and it works perfect. Both videos are with the 8psi spring.

 

Crap mine came with a -10

where the hell can I order a -6 from? I need it my friday the latest, my tune is on the 13th.

 

ams sells them

 

TiAL will swap them out for free. If you need something quick we can get you one.
