U7194 2006 Corvette running lean

[tlewismd]

I have a 2006 Corvette LS2 with 6 speed paddle shift.
Modifications: Breathless Performance cold air induction, Granatelli Mass Air flow sensor, SLP headers and complete exhaust with high flow cats.
I have the Predator U7194.

The car runs great. However, it continues to run lean in banks one and two despite increasing the fuel delivery to the max 20% with the Diablo Tune.

What should I do?
Thanks.

You will need to adjust the injector slope parameter to correct for lean codes, the fuel parameter only adjusts your fuel under wot conditions. I would go ahead and increase injector slope by 5% and see if the light comes back. I would ask you to check your long term fuel trims at cruise but currently the U7194 is missing those parameters, they will be added in the new revision.
You can however use our dataviewer to view your long terms.
But I am pretty sure that an increase of 5% will bring the trims down below threshold for causing a light.

Thanks. I will try that.
I also forgot to mention that one other trouble code came up:
P2A04: Unknown. If that makes any difference let me know.
Thanks again for your promp reply.
