I put in a ticket and the tech at BM3 said he can fix it, but it's pain to find a time that works for both of us to sync. Anyway, probably a minor issue and maybe a positive for those who like to run with ASD disabled.
That's exactly why there is no STG1 results available - no one stays there (not that I think they shouldn't, for the record), no mention of dyno and documentation of the results.

Once you start to look and hear and think, you end up moving up to FBO STG2.

In fact, STG1 and 2 are of little difference software wise.
Is it wise to run stage 2 with just an ic and no dp upgrade?
Can you do that? Yes you can. Heck ZM2 has been even running 17psi up top with bigger turbo on stock downpipe and his map can potentially be the OTS for the stage one turbo setup.

Is stock downpipe holding you back power wise? Yes, it is, but at these boost level we're really talking 10-15whp difference in peak power from 600 cell to fully decat.

Is using stock downpipe wise? Depends on how hard you push it. On street I don't see any issue whatsoever. On track sure thing in-cylinder temp will climb up more quickly and can mess up with ignition.

That being said, at the end of day, you touch cat, especially if go decat, you risk screwing up the stock refinement, as it'd be abnormally loud and smelling.
