Low Dyno? LT's,ORY, Cam
I recently had my car tuned and it seems like the numbers are quite low. The tuner had my A/F ratio at a constant 13.1 Dyno was 346/350. My car has 100k on it and the compression test was fine. I never changed the 02 sensors wondering if this could be the issue. Also have SLP ls6 intake on the way to improve numbers... What do you all think. Mods are in my Sig.
Thanks in advance,

If you were on a Dyno jet dyno and not a Mustang dyno then you are missing quite a bit of horsepower. I would expect closer to 380 hp. The problem could be many things...clogged fuel filter, spark plugs, plug wires, or any of about a dozen different sensors just to name a few. Use Autotap or an OBD ll to diagnois the problem.

I would expect your #s to be closer to 365-375rwhp (you have an A4)...but IMO, they are just dyno numbers. Just because this particular dyno says 346rwhp doesn't mean that's what you're putting down. Dynos are quite often inaccurate, sometimes they're high, sometimes they're low.
If you have a track close by, go make some passes...then look at those numbers. The timers can be wrong but most of the time they're dead-on...and track #s are what really matter, not dyno #s.
13.1 A/F is pretty good, it's a little lean but I wouldn't be worried about it.
