I idle at 750rpms in gear (plus or minus depending on coolant temp) and 
the pulse widths are between 1.5 to 1.8ms fully warmed up (coolant temp 
188F, in gear, foot on brake).  The BLMs are 124-128 depending on coolant 
temp.

The idle is no different than with the 22lb injectors.  I know that sounds 
wierd.  But, its true.  The cam gives it a nice lope but the lope didn't 
change after installing the 30's (having tuned for the chip for them).

Don't know.  Its not a daily driver.

Don't know.

I just know that it idles nice, I have great DCs, and I noticed a SOTP increase 
in performance :-D
