Supercharged 4.6 3V E85 Fueling
Hello,
I've got a 2005 Ford Mustang 4.6 3V that's pretty well modified and I just got it dyno tuned locally on E85. In speaking with other individuals with similar modifications the car doesn't seem to be making as much power as it should. I know dyno numbers vary significantly at times and aren't the best at comparing between setups but I started looking over some data for anything that might look out of place anyway.
I took a datalog today and here are some of my findings. Unfortunately, I do not have an MPVI2 yet so the data is in LiveLink through an SCT device.
What looks odd to me is the pressure drop across the injectors (highlighted blue line) and the way that my lambda value (highlighted orange line) starts to rise towards the end of the pull.
I have a Fore Innovations dual ti274 pump return style fuel system controlled with a hobs switch and ID1000 injectors.
This pull was done in 3rd gear from 2000-7000rpm.

Lambda is being logged with an AEM X series gauge and appears to vary quite a bit when WOT. Not sure if this is expected behavior or not.
Any insight on what should be expected is appreciated. I'm newer to the tuning side of things and still learning some of the basics.
