is it bad to be running the blue box and a Missing link. i removed the FMU and left the blue box, but what about the missing link...will me still running the missing link cause me to lean out?

 

the blue box was made to ELIMINATE the missing link so if u have one/check valve throw it out..if u get a check light ur wiring may be wrong..and what engine u have and ahwats the code on the side of the blue box?? (dc2,eg4,em1..etc)

 

i need to check on the blue box, but the engine is a d16y8 , im pulling the missing link today, i am just scared i will run it lean, but if anything im gunna run it lean bc the blue bloc cant see the boost becasue the missing link right?

 

the blue box uses the boost to increase the fuel supply, so if your keeping the boost from reaching your map then you dont get any extra fuel = running lean.

 

what size injectors and turbo u running? i have run t3 turbo on stock injectors. try slightly bigger injectors. 310cc should be more than sufficient.
