Injector scaling bosh OEM 0280158117 on hemi 5.7

Somebody knows how to scale the injector size on a hemi 5.7 2010 the new injectors are Bosch 550cc 52lb EV14 OEM 0280158117

Did you already get those?
Because they would not be my first choice for a Hemi. This is due to their canted 12 degree spray angle that will put most of the fuel onto the port wall before it gets to the valve.


The best choice, imo, for a beginner tuner is the only Factory Chrylser. +50lb/hr injector with a straight spray pattern which is from a Neon or Caliber Srt-4. Injector info is nearly cut/paste from the NEON tune.


Otherwise you can start with the Neon Srt-4 info and then dial in the Upper and Lower slopes of the MG/Cycle/Charge based off Fuel trims

Yes Ive already had the injectors and I used a excel program to calculate the mass and runs but the p0300 code comes when its working

So are your trims that way off that it is running that poorly? if not its because its just running poorly. What year vehicle is it?
