360 is a push, the largest injectors are for the early BBS, at 90#/hr
which is what I'm using.  I can push my 3200 # car thru the 1/4 in
13.7, without straining things, ie no slicks,mufflers, leaving at idle
etc..  I figure it to be a solid 320ish HP.  There is some room with
fuel.  Using 2" dual butterflies, in a Cross Fire Setup.
  There is an ongoing thread about the 747 (1227747) ecm used in
your truck, about tables etc.
  Might try a look in the archives, for background, look for Programming
101, for the 747 stuff
Cheers
