454 BBC with dual GM tbi on tunnel ram, MSII V3 code 2.90, MS ignition control. I have it so I can start with just a turn of key and it will warm up, start cold, start warm and start hot. My dile PW was getting down to 1.35 so I connected my vacuum pressure reducer function on the fuel regulator. Now I am using 20 psi high and 8 psi low. I have calculated injector flow at various fuel pressures and then tried to put variable "req fuel" in and not so good. When I put the lower fuel flow in the calculator I get higher "req fuel" which gives me lower VE numbers when it actually requires higher VE numbers. I have a smooth idle now within 6 VE boxes. I suppose I could trial and error each box but am hoping there is a better way. Motor is on run stand so can't drive it. I don't have VE analyze but will be getting it. How do you recommend making an initial VE table under those conditions.
thanks

Re: VE table
You may be able to rev it into other cells and get the fuel dialed in there free-reving. But you won't be able to get a complete table until you can put the engine under load - either in a car or on an engine dyno.
