Idk if my boost is kicking in late but like when I step on the throttle in 3rd gear while I drive around 2k rpm it takes awhile for my boost gauge to reach 14psi. I’m sorry I’m a newbie with 3000gts

Its been forever since I had a stock turbo car, but should be around 2500-3000 RPM.

If you have a stock car, and you're looking at the stock gauge, That's not real boost. It's a calculation the ECU makes that "should be" pretty close... (if the data being fed the ECU is correct) You should never see 14 psi on a stock car unless you have an aftermarket boost controller. If the stock gauge is hitting 14psi, you probably have boost leaks, and there is more air going by the airflow meter than is getting to the motor.
