MFI - from altitude to sea level

1972 911T 2.4 with MFi

Recently relocated from Colorado (5300ft) to sea level - had the car tuned and setup about a month before I left.

Shop that did the work was aware I was relocating, and said adjust a couple of clicks on both main and idle enrichment when I get to sea level, and that should give a reasonable baseline.

Car runs okay on it's current setting, but pickup is not as clean as it was at elevation - my question - assume I need to enrich rather than lean? More air, more fuel, therefore richer?
