Too weak of a wastegate spring for my boost levels??
I'm currently running the Large Yellow spring, which is .7bar (11.6psi) spring, and running 25psi. At about 19-20 psi the boost starts to bounce and fluctuate +/- 5psi really fast and then finally levels off at 25psi in the upper rpms.
Initially i thought it might be compressor surge, but now i suspect it might be the wastegate spring. Ive actually got a 1bar spring ordered on the way, but i would like to know/confirm the symptoms from anyone with similar experience.
thanks!

Re: Too weak of a wastegate spring for my boost levels?? (boosted k20)
I'm running the turboxs dual stage. Whats everyone else using for 20+ psi thats not a EBC??
I'm not a big fan of EBC controlers, i just want to set it and forget about it.
