Ok so ive found the issue, the restrictor pill was in the wrong place, found a diagram of how it should be and now its way more responsive, goes straight to full boost at 3.7k rpm instead of 6k rpm! way happier with it now! also found my ecu is a j2 which from what ive found out is from a V6 WRX STI RA Limited. Cheers for all of the info everyone gave me!
