i have a n/a 1987 mustang w/2.3L 4cyl that i run in the SCCA. My problem is that it runs really lean on the high rpm like 4500 to 6500. My question is can i install the ecu from a 87-88 TC along with the vam and the 35lb injectors in order to help the very lean condition i have in the high rpm range? BTW the car has a SD EFI setup. Also the head has been ported, milled and i have a larger throtle body and 19lb injectors.
