Re: Modifying VE Tables

[Len Sabatine <sabatine@epix.net>]

  If you can't pull fuel by other means , ADD AIR.  VE/MAP/RPM 
.  Depending on other variables ,
 Too much fuel pressure can be another  adjustment to trim downward , 
while tweek the VE,
  keep the ramp[s] smooth in VE tables , working a  target cell group. 
[smooth progression].
  Sneak up on ST Fuel and Let Ecm learn LT Fuel , avoids over corrections. 
All this can be time
 consuming though rewarding to get those 128 #s. Lastly , watch Ect versus 
fueling, needs to be
 consistent as well , let the thermostat cycle until ECT is stabilized . 
Take your time.   My 2 cents.
