    They must be able to flow more, don't know what cc normal Z20 LET ones are but they must be larger, say 250cc and VXR ones 300cc.

    Yup - they flow a bit more, thats all. You can only fit these with a map tailored to them, otherwise you will be overfuelling.

    The std ZLET injector's flow at 350cc & the VXR'S at 550cc. Can't wait till i get them them fitted . Also the std injector's max out at about 270bph. So any car's running more then that we the std injector's will be leaning out at the top end and that it dangerous.

    If you upgraded to the VXR injectors, would you need to upgrade anything else with it? (apart from a remap)
