Hi guys,

i have a jcw r53 from 2005 with 4-2-1 decat headers, gp intercooler and -17 pulley.

I'm planning to update the camshaft with a 469 catcam.

Can i keep my jcw injectors with this config? can i have a good afr?

Thanks

 

Keep you RPM limit to factory and I'll be fine.
It won't be optimal, and would be a good time to upgrade since the Cam will require a tune, but you won't "need" to.

 

install a wideband they are cheap insurance.
