Fixed boost leaks did have one but not anymore. Still have problem. Am on the rich side of things thou. have a greddy p/h wideband heard they were not accurate thou. But it says my a/f pegs at 8:1 which is rich as hell. But plugs tell me other wise. With white on them. showing a lean or high cyclinder temps. Im running 1.2 bars until i get this problem right. And im using the ngk br7`s. have 650 inj on a 16g.
