Re: Lowering Boost Audi Wastegate.
 

im cutting the stock spring myself. figure might as well bring the boost down and then just hold whereever with a boost controller

yeah but there's limitations to that. holding more than 2x the wastegate setting with an mbc is a bad idea.

id like to get myself a second srping.

Re: Lowering Boost Audi Wastegate.
 

If you have an acurate scale and a dail indicator you can determine the force exerted by the spring and how much deflection it has, from the you can determine the spring rate. I'm going to try this someday when I have time.
