I am looking for some advice on which stand alone you would suggest for me, I have a 2jzgte with vvti swapped into a 1989 supra, it has a t67 single turbo and ill be running e85 I am shooting for around 600rwhp (assuming the turbo will put that power down) what would you suggest for tuning? Will an aem ems v2 allow for vvti control? Or would a pro efi 128 suit me better?
