Default 1990 Msutang GT supercharged won't idle on its own after kickdown

I am having trouble getting my car drivable. I resently bought it with a super charger with 10lbs boost I believe. It will not idle on its own checked everywhere for vacuum leaks; found none. even temp duct taped around the couplings to make sure the where sealed good. I am not sure if the pipe that would usually dump smog/unspent fuel into the exhaust matters but the exhaust is after maket and there is no smog tube one it but i pluged the smog tube anyhow still no idle. I installed a Kirban adjustable regulator and no matter where it is set doesn't help. It does seem to smell rich if I turn it up high. I have a FMU I'm running the also. Right now I can only get the car running when its warm after a few tries of starting and feathering the gas. I've tried a new TPS the IAC is new EGR and EGR valve is new I tried to adjust the TPS voltage but it doesn't matter where it is it still won't idle. and turning the idle screw to far just makes the fast idle sore way too high only to drop off and not idle correctly. If I trie to drive I can only get to 25mph and that comes with poping in the exhase not matter where I adust the timing. It has a Walbro 255 lph fuel pump must recently today I got a code 87 and 95 I'm goin to change the fuel pump relay tomarrow but I don't think thats the problem. I just don't know what to do. Should I try to gut the smog stuf to make its simpler. It still has a smog pump. I am stopped I know this car has run set up the way it is before. I'm also using autolite 24s gapped and 35degress I don't think I'm getting spark blow out? 92octane gas, boost controller. What else should I do? I'm starting to miss my 347 stroker car.

30lbs injectors fixed all my problems and also ditched the FMU.
