Running crazy rich? SAFC and no boost leaks..

[EricGRIT09]

I'm just throwing this question out there, as I have searched but I would like some tips or ideas on my situation.

I am running a 14b on RC550s, rewired 190, and SAFC. I can get my STFT and LTFTs to level out fine. My problem comes when I am tuning my WOT.

First of all, I think my car is running extremely rich. The piggyback tuning guide says to start with the high throttle settings at -10%. If I were to do a 3rd gear pull on these settings, my car just bucks and backfires like crazy. I can't even get a smooth 500rpm pull out of it. Now, if I were to lower them all to -22, then it feels a LOT better. Even lower, and it feels a little better.

But, aren't these values too low for the 550s? At even -19% I can't get even close to a smooth pull out of it. It seems like other people can do a pull at like -14% and have it drive okay, just really really rich.

Anyone care to fix my misconceptions? Or give me any ideas on where to start with this issue? Or is there even an issue?

You need to start out (the high throttle corrections) at the injector correction value you arrived at from getting the trims zero'ed. That should have you running at the stock open loop fuel maps and then tune from there.
