30 lb FMS Injector ??'s

[Len Sabatine]

  Andrew ,
2 things come to mind , try swapping injectors with your friend , see if ST
goes to 160 on your car and he gets 114-117 on his car. Your friends
injectors are not as claimed and too small. FWIW.

>Both injectors are red top, black body (I emailed him a picture of mine and

>So what's up with his injectors? Does anyone have a Ford Motorsports 30 lb
