hey guys
i have a 1jz with 550cc injectors and gt35 with a .63 rear on it all being controlled by a power fc. i got it dyno tuned alittle while ago but im not very impressed with the result im now getting black all over the back of my car (which i never had before) and my fuel consumption have gone through the roof. at the moment my wide band is running at 11.2 /1 on no boost and 10.2/1 on boost which just seems to be running rich as hell. can anyone advise the correct a/f levels at all?

I like idle at about 13.5 to 1 or a touch leaner, you can stay at this while not boosting (lower revs) and about 12.5 to 1 under WOT and about 11.5 to 1 at high revs. that's generalising a lot but you get the idea.

Nor wrong, it's way to rich. I do run mine at about 10.5 to 1 for the drags, but that running 30psi of boost through it. Even 11.5 like I said is rich and you could make a touch more power if you lean it out a bit, however it's safe and less likely to detonate at high revs. And then there's timing.....
