idle problems

[bigblocktisdale]

I have ran carbs for a long time, played with fuel inj some.
the problem is when its cold it sounds great and runs good, but when it gets to opperating temp it wants to die when you come to a stop. it always fires right back up and idles but when you take off between shift it acts like it wants to die. plus it seems alittle sluggish and idles like a stock 5.0 instead of like one that has a cam in it.
it is 1991 mustang 4cyl car that I switched to a v8 5 spd
heres the combo
5.0 stock short block Fpp b cam 1.7 rockers mild ported e7 haeds with over size valves, TF track heat intake, 24lb injectors,75mm TB, 76mm mass air, bbk adj fuel reglator with guage, a9l computer, long tubes mac cat back, 4.10 gears with still the factory 4cly fuel pump.

any help would be greatly appreciated.
plus in the future I would like to have it tuned on a wheel dyno any recomendations fairly close to southwestern wisconsin.
thank you for your time.
