Is there any reason why a larger MAF is needed for Stage 3 at high altitude?

Default I guess I left out one point when saying you could try going from 85 to 83....

You want to keep your airflow in a certain range. At the very least, I'd suggest keeping it over 200 g/s. Ideally, you'd want it in the same range as you'd be wih a chipped K03 car since you are using a chipped K03 program. If it were me, I'd go to 83mm MAF housing mated to stock airbox with stock filter. That should get your readings up to ~220 or so most likely.

Good luck, man. I gotta run. I'll let others take it from here.

Default 260g/s @ stage 3- boost =>higher@ stage3 boost => larger MAF likely required ..

especially if the car ever leaves 6000ft

Default Good point. I'd want the headroom for if he ever came down from way up there.

That's why I still stick with my recommendation of 83mm MAF with stock airbox modified to mate up wit hit. That way, g/s will still be in a decent range at that elevation (225ish at least I'd assume), yet he has plenty of headroo for more boost, denser air, etc.

Default Guess I agree on that. The 260 still leaves headroom for bumping the boost... guess its low right

now.
