Just took the FD for mapping today, but they have suggested bigger injectors before mapping.
Any suggestions to the best/correct injectors, Single HKS TO4s, running 1 bar, the tuners reckon on 400 bhp when mapped???????i was hoping for more:-(

Cheers
Steve

 

most run 1300cc but i have 1600s. secondarys.

 

Go with some 850's in the stock primary rail (I sell these already modified and fresh injectors installed). Then get an aftermarket top feed rail with 1680's. You'll be good for a while
If you decide to buy the primary rail from me I will also modify your current map so you can drop them right in startup and go!
