Ive had no personal experiance but I have an old copy of Jap performance or Banzai with a 270bhp Glanza featured in it. It is running the unichip as management...Surely though you could pick up a second hand emu and have it maped for the same money as a new unichip..
Thats my car dude from jap performance and my dastek will be up for sale shortly due to changing management its mapped for a td04 on standard injectors and made 238bhp.
