Beyond cat delete

[matthewt]

I know about making the 02sims using antifoulers after removing the 4 cats. Question is, will this make the truck run lean or rich? It has a stage 2 from b&g.

Removing the cats makes your truck breath easier...ie exit exhaust gases easier. You will smell the exhaust fumes more. Throttle response will be improved.

As far as making your truck run lean or rich that is controlled by the tune.....your b&g stage two.

catless mids - probably the single best bang for your buck hp increase you'll get...... :rock:

A part of me wants to go catless mids.. But such an insanely loud exhaust and obnoxious cab drone turns me off. :dontknow: I'd prolly chose to go with a pair of high flow kitty cats instead.

Chances are--with the B&G tune, your 02 sensors have been turned off, and therefore you may not need the sims.

so what do you do with the o2 sen, ???? remove them ??

Leaner if anything. Not necessarily lean. Flowing more air.

Your truck at idle will attempt to adjust short term trims to make up for it, thus affecting long term trim, attempting to set 14.7 a/f ratio.

At other power settings, like they have said, you would have to adjust through programming. Most likely adding a little more fuel to compensate for more air flow.

Would you be safe not changing the tune - could be. Just depends on your tune now.
