recommend original evo 1,2 or 3 ecu. i think you need to change the air flow sensor as well. did this before many years ago. i cant recall much for it has been years since i sold off that car. all i can say, cheap way to have the extra ummph!
You've heard of those old stock AD07 and PP2 tyres in the market right? I'm currently running on Yoko Decibel DB 2010 week 29 tyres. I didn't realize the age of the tyre until yesterday and they are "made in Japan"...
