Here's tune and log.
I can only get it to start with if I set IFR any where from 10-20lbs
Mods are:
Holly intake
85lbs fast injectors
twin turbo
forged 6.0L
ported heads and valvetrain
stage 4 cam
dual 640lph pumps
truck has 58psi on each bank and 58psi on return fuel pressure
The log where it only cranks were with proper IFR values:
85.5 86.0 86.5 87.0 87.5 88.0 88.5 89.0 89.5 90.0 90.5 91.0 91.5 92.0 92.5 93.0 93.5
In every log the MAP sensor is stuck at 26kpa, you should look into that.
We can't view the tune because it's part of a remote tuning network, you'll need to post it again without that.
What MAP are you using?
Did the injectors come with more than just the injector flow rate? Did they come with data for the min injector pulse, short pulse adder and offset vs volts information??
If they didn't, you need that data or get injectors with that data.

Yes all injector info is input correctly except the ifr
Not sure how I did that, try this file
map sensor is a gm 12592525, it was wired wrong

So with the injector flow rate put back in correctly and the MAP sensor wired right, does it run better??
