Hmm, what size are they? Everything I am reading is the Low Impedence Injector will have way better Idle and off idle quality. If I have to run the versa fueler I guess I will just do it.
It's been a while, but I think they are around 50lbs/hr- way too small for boosted E-85. I've never heard bad things about high imp injectors. I know a lot of the LS guys are using Siemens DEKA 80lb in boosted applications. That's probably on gas though.
