hey everyone! newbie here. i was wondering if someone could help me out with my fujita SRI. i installed it yesterday myself and followed the directions exactly. fits in well and response and acceleration seems a bit better. my problem is with a weird sound on idle and low speed. its like a gurgling sound when i step on the gas. im thinking its the coolant line. there might be a lot of air in it or something. not really sure. anybody have a similar experience? how can i fix it?
