Thanks for the info Mark. Yeah, I should have a lot more room to add power, especially since it’s a Flex Fuel motor. My understanding is these injectors should handle more than non-flex as well.They look at injector data. Notice he said “might have a fuel pressure issue” since it’s leaning out. Duty cycle is probably nearing 100% at WOT which means the injectors are staying open as long as possible in order to get enough fuel through. I had that issue with my 12613412 injectors rated at 50lb/ hr but I have a blower and switched to a smaller pulley. At that point I was at the limit of my pump and MAF as well.
