hey im in the process of buying a set of gtr injectors and the resistor pack from someone on here (SAU) but he says that they have been clean and flow tested and that they actually flow 530..i thought gtr injectors were 444??
also how can u tell if the injectors have been cleaned and flowed..or do i have to take it to a professional for them to check it out??
heres a link to the thread GTR Injectors
