Tuner says wastegate spring is too tight..help please!

I know there’s a JDL specific thread however I’m hoping to reach out to anyone that could help me troubleshoot where my problem might be.



Here’s everything performance oriented installed for reference:
JDL v2 turbo kit w/ gtx2860r
Turbosmart wastegate w/ a 7psi spring (here is my confusion)
Dw 700cc injectors
Walbro 485 fuel pump
Delicious tuning flex fuel kit
Delicious tuning 3port boost solenoid
Omni 3 bar map sensor
Dyno Tuned with ecutek

Alright guys so I’ve had my car tuned a little over a month now, my tuner told me my wastegate spring is too tight and that I need to loosen it. I know wastegate springs are set values so I’m confused as to what he means. In the JDL thread some mentioned adjusting my bov, which I did but when reading on turbosmarts website this is more so to have your piston closed at idle properly and open properly. This did help solve the rpms dropping below idle which was something that was irritating me so glad that was solved. so if my spring is rated as 7psi shouldn’t my setup be able to have a minimum of 7psi- to about 14psi of range especially since I’m using the 3 port boost solenoid. When I go into the ecutek connect app my atmospheric pressure (from what I understand is my boost pressure) is stating 13psi. I do not want this much boost I was only wanting 8-10psi which is what my tuner tried to achieve but clearly something isn’t allowing him too do so. Does anyone have some ideas for me to start troubleshooting with? All thoughts welcomed I really want to get this figured out so I can actually drive my frs and have some fun with and not just having it sit in the garage everyday. If you need any more info just ask me!
