I'm scheduling my tune sometime within the next couple of weeks (still deciding on s300 vs Demon). I was going to have RC440's done at the same time and possibly upgrade from the 6lb pulley to an 8lb. I've decided to hold off on the pulley for now but I'm not sure if I should have the injectors done now or wait until the pulley upgrade. Is there any benefit to running the 440's with the 6lb pulley or should I just hold off until later and run the stockers?
