1jz motor, that this is on stock fuel and 26psi of boost and a brand new 5-speed conversion. The car only put down 430whp on pump.

might still be on stock ecu.. probably needs a standlone now. piggy backs might not keep up now.. do have a 2zj swap, or is it still a 1jz ?

Turn up the damn boost! Even on pump gas, you should be able to atleast keep up with the 600 with a T70.
