I was wondering if anyone else has hit 11psi on the stock APS tune? Since its gotten warmer I can barely hit 9psi but this morning it spiked up to 11 on my way to work, I'm on a stock block so I'm a little concerned about it.

 

Yeah...11 psi is not good. That seems to be the level where most guys popped when their boost has spiked on their Greddy kits in the past. I am surprised the actuators let it go that high. Are you running open exhaust?

 

Test pipes with nismo exhaust.. I think some tuning is seriously needed now.

 

That happened to me too a while back, man did it friggin pull. I have the Defi BF series guages so I was able to record it. I hit .08bar. No pinging or detonation so I guess im fine still. I just switched to 10w40 oil and I can notice a hug difference in how smooth the car is. I didn't think there would be a difference but damn...
