anyone mastered shimming wastegate springs?

just want to know if everyone really goes out and buys new springs for new PSI levels, or goofs around with shims, maybe should compile a list of whhat thickness equate to what added boost levels?

why? springs are <20 bucks.

and you can purchase a manual boost controller for about 20 bucks.

Re: anyone mastered shimming wastegate springs? (lazerus)

I have shimmed a WG before. The only reason was because we had no MBC and no stiffer springs and a b18b hatch that wanted more than 5 psi. It would be a waste of time to try and list all the combinations of WGs, springs and #of shims. It takes all of 2 min to change anyway.
