Do the springs in Tial wastegates have any kind of "max out" as far as how much boost they can support with a boost controller hooked up?
I have the Tial 35mm wastegate with a 4psi spring and a recently purchased Joe P. Manual boost controller. The most boost I can run with the MBC all the way down is 14.5 PSI. I want to tune it to 16psi but I'm stuck and can't get above 14.5. I was thinking/hoping it may be the fact I'm running such a low spring in the wastegate possibly??
Thanks for any info.

yea your spring is too small.get another one to replace it. you were able to turn the boost up alot already imo
