If you install one or all of the following perf mods will that change your air fuel ratio? If so will it change it enough to be concerned?

1. corsa exhaust
2. K&N cold air intake
3. from 80mm throttle body to a 85mm or 87mm

Thanks, Rob

The CPU will adjust the A/F ratio.

What they said... I would get a Predator or similar tuner before the parts you listed. That way you will be getting more power from the items you listed than the stock computer could give you.

The Exhaust & CAI won't make a difference, but a custom tune for the TB may be required. Some have had a surge show up after installation which will require the Diablo and a CMR tune.

I spoke to the top mechanic at my Dodge dealership and he said anytime you change the TB even if it is the same size you still need to program the computer to recognize the new TB.

Your thoughts?
