had 4x4 cossie tuned today but its over fuelling, the tuner tryed to adjust the co level but as soon as it dropped it went straight back up.he reckons it could be a mismatched chip and injecters. its got green 355 injectors and the chip got nec 1990 on it.if i get a new stage 1 chip can i use the 355 or will i need standard injecters.thanks

 

Pretty sure will have to go to standard for stg1 m8
Take it the tuner checked all sensors are working as they should be?????????

 

for stage 1 you need standard injectors.....

 

have you got the right map sensor

 

where can i get std injectors from ,do ford do them

 

YOU CAN USE LIGHT GREEN (355) INJECTORS ALONG WITH A STAGE 1 CHIP AND 2BAR MAP SENSOR WITH NO PROB.


check that the map sensor(normally black in colour) is working properly or that the fuel regulator is ok

 

I have 8 std cossy blue injectors for sale m8,I also have a set of dark greens with stg3 ahmed chip for P8 for sale...
