I wanna do a big bore kit and iv seen some of the 135 and 155 ones capable of being added without doing all the extras or will they still need done such as a new fuel controller and cams or should I just play it safe and buy the 155 with a nice fuel controller to handle the extra airflow I already have zoom loop exhaust and am planning on buying chimera CAI which that alone will need to be tuned but tje stock ecu should be able to handle all that basically will I just need to buy the bbk and new fuel controller to handle that but I seen ppl talking about cams and oil pumps will all these be needed
