hi i am running a 2.1 zvh on efi management with beige injectors. for everyday use it runs 13psi but when i try turning the boost up the car hates it pinking and missfiring. i think this is down to the beige injectors as i believe they are standard fiesta beige injectors which are only good for 220bhp and my car i think has quite abit more power. i hav been told there are two types of beige injectors? some that are capable of more than 220bhp? can anyone help me? or does anyone know if i can run any other injectors on efi management? i dont want to go cossie management i would be gratefull for any help cheers

 

beige injectors are only good for 220 hp and they are shit anyway,ian at fiesta frenzy does chip injectors an map sensor for Ł630 if you dont want new management

 

cheers i will give them a call

 

why dont you take it to msd i sure he sort it out for you
