Heh. I didn't even see that.
I find a good solid number for most of the map, something that might hit a stock-ish boost level in a hurry, then start ramping gently to 4500, then ramping super steep to 5500 to fight off the taper. By then and up, everything is 500. I run the ABC closed. I've been tinkering with the lower loads to give the boost a little bump to help me out of auto-x corners and situtaions where I might need soem help getting the rpms back up quicker.
I think opening the ABC will get a little pressure off the wastegate and halp spool some, and I've replaced all the bleedoff hoses that run to the FBC, and vent back out to the turbo inlet.
I was thinking about plugging that inlet nipple and running the FBC bleedoff to something like valve cover breather, using a much shorter hose, or does the turbo inlet hose provide enough vaccum at that point to be benificial for venting wastegate pressure? I would have gone with the Perrin or GM replacement solenoids by now but I keep finding little tricks to get the FBC to do what I need.
