Hi all. I am from Canada, and loving my recently purchased xk8.I want to increase the performance, and was thinking of a chip, intake. My technician said unless you do all 3 (intake, chip, exhaust), to forget just doing 1 or 2. I DO NOT want to modify exhasyt as I dont want extra vibration/ noise. Is "re-mapping" the same as a chip?And, could I get away with a remapping and intake without exhaust? Any advice is appreciated.Maybe I should have just gone with the supercharged xkr?
