Just off the DYNO today, she pulled 552 RWHP (SAE) @ 6300and starting leaning quickly around 6500. Running 2003 tank and dual pumps, with a 3.5 INCH UNIVER MAF. Stock rails and regulator. Also got 55LBR H.I. Injectors.

Anyone got suggestions?

I had my REV LIM removed, but I can't run her above 7,050 since she will be too lean at that point. The engine wants more!!! But she ain't getting until she gets fuel. If fuel is the issue

Maybe larger injectors? Hate to go there since these 55s cost big bucks already, hate to see what 65s cost. Maybe upgrade the rails??? Wondering about that UNIVER MAF too.

I ran into the same problem using 55's, stock rails, 03 pump & tank, NO boost-a-pump. I replaced the rails and now have great A/F (11.5) out past 7300 rpms.

You know those damn d1sc' - they have a nasty habit of making too much power!
Seriously though - I think its your rails and lines. Im in the process of upgrading everything fuel related, and those stock rails simply are not going to cut it.

I have CPR fuel rails, I think they came from Modular Performance.
