I thought I would try to give back and share my scalings that I did for my setup on my 05 WRX. I have the 16bit ECU so my scalings are scaled down roughly 75%. I have a GT3071R rotated turbo and FMIC and I am running 20psi. I used RR for the MAF scaling tab and it is within 4%. I had changed both of these at the same time and before I was able to do any scaling on the stock injectors or MAF so I just got my MAF scaled properly. My light blue top feed DW850cc injectors are using the stock latencies. Here are my scalings and I hope it helps someone else out.

What is the inside diameter of the MAF housing, and what is the highest MAFv (or g/s) that you've tested?

Thanks!

I usually end with higher latencies than stock using DW850. Somewhere between 0.85 and 0.95 at 14V

Did anyone have any issues with these parameters?
