gurus please help!!! desperate

ok im going crazy.. ive been working on my 88 gxl forever... my motor has very good compression. im getting spark.. ive gone over my harness over and over and all the actuators and solinoids and coils and tried different ecu's and maf's (yes same number as stock) i removed my oil metering system and have 2 stroke, i have new plugs like 3 different sets due to fouling, new wires new everything.. i checked my entire harness engine and ignition.. and found no problems... basically the car sucks.. no power will rev.. but slow.. funny sound from my intake, all the injectors are working.. i had them check and flow tested and they are withing impedence and flow checked., now this is an odd car.. its an s4.. but it has high impedence injectors, and it doesnt have that injector resistor thing most s4s do.. the holes where it would bolt up are plugged and the plug is just not there.. i went over and over the factory manual specific to 88 and could not find it, i tried two n37 ecus and 2 different n36 MAF meters.. i dont have any vac leaks.. ive gone over it and did all new gaskets my block off plates are perfect and i have been over them about 10 different times, i removed the vac tree and have been slowly hooking everything back up just to see if it helped.. so i got my BAC back the 5th and 6th port and the air pump is gone alog with the actuators and the air controll thingy.. i made block offs and plugged the holes with JB weld.. i capped off all extra nipples so the only lines i have are boost sensor and fuel pressure regulator.. ive tried 2 different rails for both primary and secondary.. there some closed thing behind the dash for the harness from the ecu to ignition harness i cant get to.. my coils are good and i have like 5 different CASs all checked out and sutch.. the car runs.. but runs like poop... i cant run a diagnostic i dont have the reader.. can any code reader work? its not OBD tho? what can i do???? basically it sounds like the timing is so FUBAR its crazy.. but i have the CAS installed right with the right marks and sutch and when its sorta idling the marks are right.. what do it do!!! take it to mazda? they want 200 bux just to plug it in for 5 mins.. and they wont let me talk to a tech even for 2 mins.. anyone have any ideas??? this has been 4 months like this 2 different motors and im still going crazy... i used ALL my originall harness and ecu and injectors and everything.. so im not crossed up at all.. anyone please do you have any ideas??? id be willing to pay money to have fixed or and idea of whats wrong.. i live in eugene oregon and there is noone here that will help me.. one guy is good but he never returns calls or anything and i have a drift even in 20 days and im going nutz... please email me or respons on here or hell call me even if your a guru.. please im begging.. 541 517 7660 my name is matt.. hope to hear from someone

well, next time use paragraphs, and it would be easier to read and figure out.

#1 The 87.5 and later used the high impeadence resistors.
#2 the N37X and N36X ecus and AFM are for S5 cars. Do you mean N327 and N326??? If so, either will run it, but the N327 would be the correct ECU for 87.5 and 88 non turbos.
#3 it sounds like its running way way rich- how much 2 stroke oil are you using?
#4 you probably also have a vac leak. What is the vac in/Hm at idle?
