Building a turbo truck and I just can't wrap my head around all the terms and math that comes with calculating the new numbers for hptuners. Truck has a 220/224 112 +4 cam in it with 127lb iniectors and I feel like there's gotta be some driveability or power on the table by adjusting this since the injectors are spraying for such a short time (1.8-1.9ms at idle). Not having any luck on the hptuners forum.

i've used dsteck's calculatr before, but with much larger cams than yours

you may also look into min fuel mgs and transient fueling

im not sure which injectors you have but most 80+ lbers are pencil pattern and need some tweaks transient to drive right

I wish I could tell ya more, but I'm not the best when it comes to that stuff
