My focus in tuning has been fuel pressure related but mechanical since my fuel pump is stock and the holley AFPR stock spring was too weak (only 22lb/inch, replaced with a 80lb/inch). Vacuum referenced and now the BLMs are getting all messed up. I let off the throttle and every time the BLMs go sky high and sometimes hit the 150 limit while just cruising. I'm going to raise this and see how high it goes because under normal driving acceleration the BLMs are always right between 126 and 128.
The fuel pressure is at 12psi with 40kpa and 18psi with 100. A swing of 6 psi makes for a big change but is it healthy to let the ecm run BLMs in the 140, 150 range on decel or what? I figure that during decel the BLM doesn't matter because even the computer has the built in Decel fuel cut off!
I've been using logged data from winaldl and tuning the VE tables with the BLMs reported ONLY while TPS is increasing, never decreasing.
Any suggestions?

edit; I forgot to mention that my idle has smoothed out completely even with a stock calibration (best with slight VE and IAC tuning).
