So i'm new to this site, I got my 1999 v6 2.5l automatic cougar when I was 16 and iv always wanted to make it a SVT. I might of done a half ass job but this is what iv done so far. SVT intake upper and lower, SVT throttle body and hoses, Throttle cable, SVT mass airflow. I have not yet done injectors they are still stock cougar. my car does have a fuel pressure regulator on the rail. Id like to add SVT injectors and pressure regulator if it will make a difference? The car runs but it runs rough and im sure how it needs to be programmed. My question is what is the best way to program this car with all the changes iv made. I did not change the cam. Is there a programmable tuner I should use Or a special was to program the ECM with what iv got? Please let me know as now I have some free time to finally finish this Project.
