Just wondered if anyone knows what duty cycle the injectors on chipped LCRs usually run at, and what psi do most people upgrade them?

they're fine on a stock turbo, and even a hybridised K04

people only change them when moving to larger unit (so >320bhp)

so if you're running a stock turbo you're still a fair way from that.
 
does any one know if the cupra R injectors will fit and work on just a 1.8 20vt cupra?

No they don't fit straight in (sorry Willie) you will need to change the injector seat, i know this because when i changed the Mani on my LC to the LCR one, the injectors wouldn't fit so i had to put LC one's in, they are a PITA to get out too.
