Well everything was looking up, I had my b18c1 ready to put all my turbo gear on but replaced the throttle body gasket because I believe it was leaking a tiny bit. Anyhow I had my 550s installed, 3 bar map and Phearable ecu with my basemap. I'd start it up and the air/fuel ratio would be around 13.2 at idle and get richer as the throttle increased which i thought is how it should be.

Anyhow I replaced my throttle body gasket and put everything back how it was and now I have an air fuel ratio of 15.0 at idle with the same setup as I had before and if you increase the throttle it goes up as high as 15.4

I put my stock ecu back in, stock map and stock injectors and again it was around 15.0 and went up as high as 15.5 with a blip of the throttle. And got a code 20 ELD code which I don't believe has anything to do with this.

It idles perfect but the only thing I can think of is a vacuum leak around the throttle body... What does everyone else think?

Thanks,
Chris
