ok im in the process of installing my sr in a couple of months. wat i want to know is if i run my arc sidemount i/c with s15 injectors and a walbro will i get the same mpg running stock boost that i will get with the stock injectors? reason i ask is that i want to throw on the s15 injectors while the engine is out and its easier to work with, but if i get bad mpg without the added benefit of raising boost then i'll wait a while before i raise the boost and throw them in.

If its tunned to the correct A/F ratio no it will be the same at the same boost level, again only if its tunned to the correct/same AF ratio
