power ecu
#4
Possiblyto better to get a boost controller and get what power you require from more boost, if you use thre right fuel and have the gauges for safety ( AFR, Knock ! ).
Best of all is a proper uprated ECU, like the link or Apexi PFC etc and get it all mapped in!
Safe smooth and powerfull!!

My V2 sti has a Z4 on it. It also has an eprom chip in it. Boost 1.1 and very quick. I'm sure you should be boosting at 13.8psi(nearly 1 bar). I'm a bit confused now about what a z4 is off
