Does anyone know the PSi rating of the spring in a -31 Actuator looking at getting one of these;

But I haven't got a clue what spring I need

 

how much boost are you running

what type of boost control are you using

 

The -31 is unique and no spring offered by anyone other than garrett is the same.

 

-31 is good for a lot ov boost fella....i've got a ut t38 and it peaks at 30 psi and holds 28 all the way to 7k.... stu at m.s.d sell's them at a good price

 

I'll be going for a -31 item now, I quite liked the look of the Forge one but its how it works not how it looks thats important. Will using a -31 on a standard tune cause any probs? my actuators shafted and I need a new one I do have engine mods in plan (I've had a set of dark greens for a year and half sat in my bedroom) and I don't want to be having to buy two actuators as monies a bit tight currently.
