Your profile says you have an 18g...but how the hell are you not maxing out the STi injectors is whats picking my brain
. Why did you get it tuned with such small injectors?
You will need a complete fuel map retune, dont skimp out and get it done right with a WBO2. Since you were probably maxing them out, the boost map might have more potential which means the timing map needs some adjustment. Looks like you are facing a complete retune.
