I bought a used supercharger and installed it in my car. I can't properly tune it at the moment. I use UPREV PRO TUNE. I don't understand the calculation of K FUEL MULTIPLIER in UPREV, and the correct way. MAF correction。

This is the original K FUEL MULTIPLIER of my car. I replaced the 600CC injector. What formula is used for calculation?

The guys at UpRev wrote a tuning guide, you might want to read this a couple of times...it really helps to grasp things.
