Holley Sniper X Flow Base Fuel Map

Are there any EFI guys here? I loaded basic engine information into the Holley ECU & below is the base fuel map it set-up. I'm pretty sure the white fuel cells/blocks are not good in the higher boost/rpm range. Plus, I'm not even sure about all the other cells/blocks. Any body have any insight on this fuel map?

First of all you are looking at volumetric efficiency map. Click the box that says conversion and you'll get your fuel map. I've installed about a dozen systems on street vehicles and have a system on my own daily street car. I have an X-flow 8 injector that I am installing on my Bracket car this winter.

LOL! I'm not very smart with this crap. Our system is the X-flow 8 injector going on our ProCharged bracket car. I'm new to the supercharger crap also. Thanks for the tip.

There should be several folders with tunes for a lot of combinations. There is also one for a supercharged SBC at 14psi that should provide a good baseline until you get track or dyno time. The one I found is in the ...\Global Files\Custom Cals\GM\SBC folder. The 350-383ci Supercharged 14psi.hefi file has a way better fuel map with the pressure axis that has much better resolution during boost. You can also change the Pressure axis to kPa which will always have positive numbers for pressure. Just for reference, the white cells with red numbers mean that the fuel pressure and injector size will not support that fuel volume (PPH). Good luck.
