been getting some advice on the best way to go on me upping my bhp on me 9ix from 370 to around the 450 mark and to be honest getting very differnt feedback from tuner to tuner (no offence to anybody). a lot of people seem to get uprated pump at the begging of modding but them a lot of tuners are recomending injectors but not puel pump?
What are others people opinions on this subject? dont know if this makes any difference but its a JDM motor
