87gt5speed

does anyone know if i get a twEECer for my 87 gt if it will allow me to tune the speed density system for bigger injectors?? or would it be better to do a mass airflow conversion and use a calibrated MAF sensor for the injectors i get?? or would it be best to get a twEECer do the MAF convetion and i could tune it better than it you can the other ways???

it would be better to use a tweecer rt and a A/F kit to use as a stand alone than dealing with the SD'puter

Yes...........just make sure your EEC Program Code (if other than DA1 or SD1) is also covered.
