Early 99 injectors
 

I just replaced my gp's and also changed out injectors I had AB's and went to AD's it feels like i might of lost a little get up and go. Any ideas

how long ago did you change em? may need to work all the air out of the system still

A couple things come to mind here...

You could just be experiencing air in the system from changing the injectors within the last 100 miles or so...

or you put worn AD injectors in place of better condition AB's...

You went from 120cc injectors to 140cc injectors.. Hardly worth it in my opinion but to each their own.

had them in for about 400 miles now. the injectors are brand new Alliant set all AD's and 1AE. Iam running early 99 IDM with hyper tec 50hp program air aid air filter and 4in exhaust
