Ok so I have a 97 sc300 na-t running afc and aem tru boost........my car was running great........then my turbo took a dive so I had a shop put.in a new one for me ........ Now my boost gushed is goin crazy saying I'm boosting 25psi even at +50 all the way accross leans way out at full throttle n starts pinging ......needless to say I'm driving my car like a grandma now.......the shop says my car needs more fuel.....ok at 25psi I understand but I shut the boost controler off running my 10lb spring in the wastegate but its still boosting to 25psi anyone have any idea what's.goin on?????? All they did was swap the.turbo its just weird .it was running fine before and my gushed would stay pinned at 10psi now its bouncing .off the walls.......I have stock objectors but.from what I.understand they can Händel 10psi

Yes the stock injectors will handle 9psi. But like lexforlife said, we need more info. Rundown of your na-t setup, turbo size, did you lower compression, what WG your running, etc. etc.
Double check all your vac lines, specifically from your boost signal to the wg.
