Default S-afc Strange Problems *no Newbies*

OK,Civic Coupe 1998,my motor is d16y7,supercharged with a Garret T28,440cc Dsm injectors,Blitz blow-off & intercooler,Eagle rods and pistons,running 1,3 Bar(European measure).
To the question now:
My settings were tuned on a dyno and setup was done according manual all this double checked and all ok.Now what happens is suddenly after 15 second on engine running idle my a/f ratio meter goes from lean to rich every second,and i loose 1200 rpm.For example i hold it on 3000 rpm and when this happens the same time the a/f ratio goes lean to rich and motor goes to 2000rmp(lean) and 3000rpm(rich).Only one thing comes on my mind do i need a resistor box for the injectors?Dsm(3 ohms) original(12ohms),i don't know what the hell is going on,i also replaced the controller(s-afc) but still nothing.
Please help.

agree with above.

but to fix your problem, you need a resistor box for your injectors. the peak and hold 450cc dsm injectors are going berzerk with all the extra voltage you're sending them.

Check your O2 sensors wiring.
