What model?
Full mod list?
What do you mean by "tearable air to fuel"?
Do you have a wideband O2 setup? If so, what specifically are the air fuel ratios?

I think the username means a TII, in which case it's 3800 RPM and 2" of vacuum.

How do you know the A/F ratio is wrong?

You're not going to have a very reliable setup running any upgraded turbo on a stock ECU.

What injectors are you running now? I'd suggest at least 900CC secondaries but you won't be able to tune those very well with the S-AFC.

A standalone is the way to go. If you continue this way, you will be building an engine very soon.
