I am trying to determine if there is a noticeable real world difference between the

Fuel Injector Clinic 1120cc Low Impedence Injectors (cost about $350)
VS
Fuel Injector Clinic 1100cc High Z (cost about $550 w/ resistors)


I know that the High Z is newer, and better. I understand that the main difference if any would be found in idle.


But can anyone with experience say its noticeably worth aprox. $200 more. Where like anyone else I could use that extra $200 for other go fast parts?

 

If the budget is there, High-Z injectors are the way to go. But in that size, it's not a big deal. You'll be fine with the 1120 low impedance. Where it becomes a lot more important is when you into 1300-1400cc and bigger.
