Like the title says, is it going to be okay or is it going to run lean or rich. I believe the 12:1 is going to be way to rich. Let know your opinions.

Depends on the T3. Most factory T3 turbos are very small, and a 10:1 riser with a decent fuel pump would probably be fine. I'd keep an eye on it, though.

its actually a big t3 63 exhaust and 60 a/r. I have the 255 walbro high pressure too. Should I just go with a 12:1 instead? I don't want to be running so rich too.

Why the aversion to running rich? When on stock pistons, rich is *good*.

trying to run it so I can get some extra hp without being too lean. I just don't want it to flood out and stutter at wot. Otherwise I know running rich is not bad.

Don't worry about it stuttering at WOT, it shouldn't do that even with a 12:1 FMU. If you have stuttering at WOT, you have a problem elsewhere most likely. Like Dino said, rich is good on a stock engine. I wouldn't want to chance running lean just for the thought of having 1 or 2 hp more possibly. Not worth it in my book.
