Hey guys, i brought a 350z turbo, the car didnít feel that it got power. However i took it to the tuner and it only made 150 on the wheels on 9psi, so we did a boost leak, compression test and checked the exhaust but everything worked fine. The tuner checked air/fuel ratio everything worked well, he did put the boost up to 13psi and it made 194kws. Did anyone face that problem before or anyone can give me any ideas?
upgraded fuel pump and injectors.
T28 turbo (HKS TURBO KIT), the turbo is working fine no play shaft.
Hks oil sump.
