  1. Tuning, Technical Questions
    Hello, Got a r33 rb25 and it was running stock turbo at 12 psi. Car seems to be a little sluggish and free revving won't go above about 2psi. I used to get 12 psi at about 3500 but now it's struggling to hit it even at 6k! Is this the turbo saying good bye or is there a more likely option...
