wheresmycoupe

So I'm having an issue where my car almost stalls coming to a stop. It drops down to about 500 rpms sometimes lower and The oil light flashes. Occasionally while driving my cel will blink 2 times at most. The temps have been to 100 Celsius during normal driving.

Set up is red top Sr With 550 cc inj. 50 trim .48ar. Power fc.
However my tune is for 550 ' s and a 50 trim .63 ar. I blew the turbo so the .48ar is just a temp solution until mine is finished being rebuilt. Idiotic I know.

Could that be my problem^^^ or could be something els like a bad tps and the oil light flashing is just cause the pressure is low when the cars about to stall?
