After doing my upgrade on my EL XR8 (link in sig) would I see any more benefit from more custom tuning from getting a bigger fuel pump and fuel pressure regulator to the system without changing the injectors. Nothing more mechanical will be done to the engine its staying in its current config.

If there was an issue on the dyno with the AFR's then yes, if not i wouldnt worry about it, unless you are going for a bling alloy FPR.

Nah no issues with AFRs.

I'll leave it then. Thanks for the info.
