Fuel rail and injectors


Work in progress
Hi there again lads and lady's need some more help with my s3 I have the bam 225 engine and Iam about to get stage 2 remap and was told to upgrade my fuel pressure regulator and I have now would you recommend changing the fuel rail and injectors aswell or would they cope as the pressure regulator is a 4 bar one now and I'm gonna be pushing 290+ with the remap. Cheers again

You shouldn't need to change the FPR unless going past stage 2 the same applies for injectors.

I am stage 2 running the OEM 3 bar FPR and all is good
