SOOOO . After a year of driving my Q for a year . Ive changed the tires to Toyo ,added forged rims and lowered with Ark springs . Now I’ve decided to do some modding . I have ordered AMS LDP and Stillen CBE ( can’t wait for it to get here ). But I’ve done some digging and some say you need a tune some say you don’t. I don’t want to get a Ecu tune yet because of my warranty but found JB4 as a option . I understand it’s a boost and not flash . But my question is will the JB4 sense my exhaust and LDP and calculate the map for me ? Or will I have to input the numbers in my self ? Will i have to re map after let’s say I add CAI in a month and then HE later ? And is the JB4 enough to tune any of these part to even start with ... someone help !
