Help Please

Well all of the sudden the Z is acting crazy. Not sure what the cause is but need it fixed ASAP. Any and all help is appreciated. Car is a 99 Z28 A4 Car. Pretty heavily modded. The problem started about 2 days ago. When cranking the car it takes about 4 tries to get her to crank, Eventually she does start but takes time to build up to 900 rpms. While driving the car...if a give it alittle gas she does not respond. If I give her alot of gas she hesitates then sputters. No power what so ever. If at idle or parked and I turn on the AC the idle goes down to around 400rpms. Then oil pressure goes to around 18 and she may or may not stall. I have exhausted every idea I can think of. Replaced the Fuel pump, fuel filter, spark plugs, wires, checked all rockers and springs. I am lost now. Any suggestions???????

Have you checked for a gross vacuum leak?

Did this problem come on immediately after any
particular engine mod / underhood activity?

No major vacumn leaks......I do have AutoTap but not completely sure what to be looking for? As for the problem. I have had no issues sinse install of the major components 3 months ago. Then one day it started all of the sudden?
