Yes agreed, a reflash will do the job, but will not do the best job. After forging the motor, obviously you want to chg the turbo so on and so forth. A lot of motorsport features will not be available to you on a reflash.

This guy drives his car hard LOL. (I am so glad he uses the stage 3 exedy)
But he definitely needs a forged up new motor.

But most imptly, see how your budget is and have a talk to some of the workshops and determine what suits you best.
