This should put me somewhere in the mid-340s using my VD methodology. They also confirmed that you can use the base S2 tune with just an FMIC, and that S2 is more analogous to the n54 S1+ tune.

I sent MHD all my data, and am going to wait until they have a chance to review, and see if they want me to do any further testing. I'm most likely going to go to S2, but will wait until MHD directs me to do so.

More to come, I'm sure.
So you could do stage 2 with stock cat? Just need a fmic upgrade?
