ok i recently swapped out the engine in my 86 trans am tpi from a 305 to a 350. im ordering the new injectors and i was informed that im going to have to get a new ecu. is this true or is there a chip that i can install in the ecu to save me some money? If i do have to get a new ecu does anyone know who makes a descent yet cost friendly ecu for the 86 trans am. thanks..
