    Accurate Injector PW table for larger injectors

    Is there a way to get an accurate injector PW table? I did some scaling and blending and seems to be ok but I don't know how accurate it is. Seems to be the normal strategy. I included my tune if anyone wants to check how i'm doing for 60% over, just trying to get it to run clean now. The injector flow chart I got from DynomiteDiesel doesnt help much except in power region, this is what it amounts to...

    For what it's worth, this is what BD diesel lists for their 53% overs. Not that it's an exact match to your injectors, but you can do some comparing at least.

    Nice find.

    I put that data in to compare to mine and interesting to see where the differences were. Comparison table below. Tested it out in the truck and I think i'm gonna run with it for now, probably has less total error. Wish there were more accessible tables for us to use, can't imagine tuning with 150% nozzles.
