Have you gotten anywhere with these injectors Outlaw? I am running a set of SEP 850s and while it may not be directly related to the injectors they have been nothing short of a total pain in ass to get tuned. Very inconsistent VE table behavior and the usual big injector problems of rich deceleration and idle. min fuel transient. In my opinion you should be tuning your car at 58psi.
Here is where I'm at right now. The car runs good, has decent medium boost Air Fuel ratios and seems to be fine cruising around. It has a return to idle problem that I'm slowly working out. Stays high for too long or dies when I push in the clutch coming to a stop. Trying to find a happy medium. Other than that it's pretty good. I'll do a follow up video at some point. Our final race (AX) of the season is in a week so I'm working on the details for that.
I agree that my fuel pressure isn't right. That could come back to bite me later. Currently it is about 50 and rises with boost pressure. My duty cycle is less than 40% at 8psi. So I probably should have done the 850s like you did. I'll pay more attention to erratic VE table and see if that's happening. I still have LTFT STFT Long and Short term fuel trims turned off so that might smooth things out even more when that gets turned back on.
I wish I could help. I'm just learning how to tune this myself. Are you using HP Tuners? I would suggest contacting SEP and getting their spreadsheet that shows the data to put into HPTuners. Then depending on your skills, you may want to contact a Tuner that can do the fine tuning.

@@budgetoutlaws9978 I am running 11 psi on an LS1. Even with 850s I'm barely at 49% at max boost. Are you running a GEN 3 411 PCM?
@@PNW_Car_Mods yes 411 or for others following also known as a P01.
How are the injectors doing still ?
They work fine. I had two tuners that didn't want to work with them. I ended up tuning it myself. Not the greatest.
Hi I was wondering if you would be able to help me, I have the 1500 sep injectors and I can’t get the car to idle properly with my ls engine :-(
