Air fuel ratio

[baylor2010]

I have an 06 gt (auto) witha c&l intake and diablo programmer. 1st question is if i add a high flow catted x pipe how bad will that lean out my fuel to air ratio and if it does how do "I" myself fix that with my programmer (not having to pay for someone to do it, i have access to a dyno).

Thanx for the input

It depends on your current tune and A/F it is currently at. Every car is different. The mods in my sig, the a/f was okay until the headers and the o/r h pipe I needed to add 2% rich at wot. When I first install the headers and drove the car. The a/f was 13.2 at wot, which is a bit aggresive. then after added more fuel the a/f was 12.8 at wot. if that is all you r adding I would say that you wouldn't need to add more fuel. But like I said it depends on the current tune and where the a/f is currently at. Have you ever had the car dynoed? I would say that you are okay adding the x-pipe without adding fuel.
