Why is this not your most immediate concern, rather than your tires? More boost than expected is not necessarily a good thing.

...your spring pressure on the wastegates should be pretty close to your boost pressure if not you need to find out why ..could be vacuum line not connected right ..or could be have came off ..got cut ....and I would verify which spring in in the waste gates.....the traction isn’t really something “wrong” that needs to be fixed ..it’s a effect of having a boosted Z ...you just need to learn to use it ...but not knowing what boost you should be running and just running whatever it gets can cause that’s what it does to me is a much higher priority

This is my first boosted car and tire setup. I can say it's ALOT better than the stock nismo tires. It doesnt hook in 1st or 2nd but I'm pretty sure I need the driver mod. After I wear these out I will probably go with a 305/45/18 next.

Nice. What fuel are you using?

Also I recently upgraded from 275/35PSS to 305/30 RE71R.

All I can say, is its a huge difference. I feel much more safe on these new tyres!
