I have been thinking of getting a better fuel rail for my FN2 maybe AEM as they are reasonably priced and iv had their products in the past which have proved to be good quality.
Iv never moved further than exhaust and intake on my engines due to insurance and age etc so iv no idea what to expect.
Heres my ques?
Will I notice any improvement?
Which fuel rail is best?
Will there be any point with the only engine mods being HKS RSK and Miltek non Res?
and any general advice
