    Yes, it does remain at 100%, but it also seems to be the point where the fuel pressure starts to drop shortly after it hits 100%. I commanded it to be 85 psi to see if it would allow it to at least...

    The pumps should support the current power level, i wanted to install an external regulator, but he wanted to cheap out and try the $400 option lol. Something in the fuel pump control module is...

    Don't forget to re-scale your timing table and lower your spark timing, copy high octane to the low octane table too. Your MAF should not be that far off, the changes were minor but definitely check...

    Well you can double check with them on that, but that is what i found under LS3 90 LB/HR. As far the misfire issue, that cylinder 6 spark plug has a lot of black spots on it which is usually an...

    You're welcome. The injector data is not right, flow rate, short pulse limit and adder are a little different than what is in the data sheet. I changed the data for you. Make sure when you are done...

    Ok, was trying to let you know what you were getting into lol. Looking at the log, there is no way that air fuel ratio could be "fine" look at the BARO sensor it is reading boost pressure, The...

    The result of low spark advance would be giving up horsepower and producing higher EGTs by igniting the air fuel mix too late. Rough maf curve is going to give you incorrect air fuel ratio,...

    The file you posted is not stock. To be honest, that file needs some work. The maf transfer curve is rough, need to calibrate VVE and re-enable it, spark advance is low.
