...I have 850cc injectors and an aftermarket FRP set to 3Bar on idle. Car is running about 350Bhp @ 1.4bar

Its obviously been mapped for these injectors, but would the parallel fuel line mod benfit me regarding No3 running lean and melting?

 

You could simply run the fuel feed in the opposite way through your existing fuel rails to ensure No 3 gets the fuel supply first..

 

Would that not mean that cylinder No2 would then be last to feed therefor potentialy run lean?
