from what i understand it depends on if you have a high or low impedance injector i may be wrong but high impedance injectors do not need one but low's do if i am wrong please correct me

I'm pretty sure that tuners like it to be kept, just so they are able to tune the pulse width of the injectors. Like above, I'm not 100% entirely sure though.
