Do you have a AFPR to control fuel pressure? you could def tune it out close to perfect with one if you dont already have one.
If you dont, heres one if your on a budget, I used one on my rb20det it worked perfectly, and by looking at the sr20det the fpr is very similar.
If you want to do it the 1000 times proven way there is always the nismo afpr, good luck bro.
