"Bosch EV14 LS7 style injectors" Did you notice the "style" moniker in there? They use FiveO Motorsports even says so in their site if I remember. Either way, not all injectors are created equally, period. If you lookup Injector Dynamics it'll be plain to see. What they do is run through batches of injectors and chart their performance through the range. Once they are charted out, they pair up ones that perform alike to a very high tolerance and sell you the set that is matched best. There is no substitute. Brett Dempsey has a video up of him having a 2.0L 4 cylinder motor idling perfectly on 2200cc injectors, that's unheard of. Although *theoretically* you *should* be able to tune them like any other injector, that is not the case. Responses from different types of injectors are different inherently. Go I.D., get a *good* tuner to dyno-tune, call it a day. ;-) (Take it from someone who wasted $150 on the shittiest tune imaginable)
