Injector Question
 

Hey everyone,

My current set up is an MSPNP 1 with RX7 460 High Imp injectors, on my stock 1.6. Cur runs pretty good, idles at 900 rpm and low 13 AFR, get the odd misfire and a bit of rpm fluctuation at idle mostly when loads are on(rad fan, headlights). I can get 24-28mpg depending on how i drive it. What im wondering is would there be a huge improvement going to RX8 or GT500 injectors? I know the RX8 are a generation up and the GT500 the latest tech. Being that its MS1 and batch fire could i get it to idle in the 14's with newer injectors? I have flipped through a lot of threads on here, lots on different opinions.

Any info is appreciated!

The short answer is maybe. How important is having a slightly leaner idle to you? That's going to be the real question.
