If tuned with a wideband and Zydine or Ghettodyne ecu can it run 8 psi. Well because I may have ordered the wrong spring for the tial. I have a 5 psi but the wastegate opens at 3 psi, So if I get a 10 psi spring it will open around 7-8 psi. But will the motor handle it properly tuned on the dyno with 440cc injectors and warlboro fuel pump and dx to si manifold. Just don't won't to blow the daily driver. I don't won't to drive the red rocket everyday. thanks.
the motor is a 1989 dx d15. Where to stop.
