Because the stock EFI system cannot compensate for the changes, so the engine will simply run very rich. This has nothing to do with the rotary, it applies to any engine.
By increasing airflow, i.e. intake, exhaust, porting, etc. Up to certain point the EFI system will easily compensate for increased airflow, and NA's don't reach that limit without major mods.

Have you checked the bulb in the interior light? Have you checked the 7.5A ROOM fuse?
Search the 2nd Gen section for "cold solder" and you'll find lots of info on problems with the warning light and clock cluster and how to fix them.
What if i gave it a hotter spark .
If you want more power, you need more airflow. You don't need to worry about anything else yet.

The reason your car is bogging after 3800 is the 880cc injectors and pump. The secondaries come online @ 3800, so at that point your fuel map is so rich, I'm surprised it even runs at all.

The hesitation is caused by the mixture suddenly going ~35% richer when the secondaries come on. Get those damnned things out, they're not helping at all, only hindering.

You'll have a REAL hard time reprogramming a S4 N/A ECU. Or any N/A ECU for that matter. You should sell the injectors and pump. Then you'll have enough money to get the appropriate stock parts, and maybe even a few goodies. Think smart.

I have never sold anything online as of yet . So should I try puttin them up on E-BAY or somthing . I know they were expensive as hell and an apparent waste of my money and time . I suppose I should have thought this threw better . DO any of you have an N/A if so are you running the 460cc injectors and what kinda power are you seeing .

I hope you still have the old injectors, because if they were just leaking then professional cleaning will restore them to near-new condition for a fraction of the price of new ones.

Yeah okay im stupid thats prolly the only reason the car even runs is because it still has two stock injectors on it . I looked before in my repair manual and it didnt say anything about four of them . Thats great just great !!!
I went out to take a look are they like impossible to see with out taking it off cuz I looked pretty hard and didnt see them ?

This info is easily found in the Factory Service Manual. If you don't have the FSM, click here and download it in PDF format for free. For future questions, the FSM should always be referenced before posting, as many times the answer will be in there.
You have to remove the UIM to get to the primary injectors, as you'll see when you read the manual...
