hauss, bigger won't solve those problems, sorry. Probably make it worse simply due to the 950 being TOO BIG. Air velocity will be slow and then compounding with less air. Nothing good will come of this.

I've run from a 700 ft tune (MI) into the Rockies but, much higher than 8,000 is a problem. I've had to drop jet sizes to average the tune out. Usually 2-3 sizes down takes care of things.

What you need to be a bit careful of is tuning for altitude and then dropping to sea level, this is where it will lean out, maybe dangerously so.

If changing altitude is a regular event you really are a prime candidate for EFI. Ouch, that really hurt but the truth is often uncomfortable.
