Still tying to determine if something is off with my setup. With my 98mm, I was hitting 7 psi in fall/winter/early spring here in Seattle. As soon as I swapped to a 96.mm (still early spring) I only saw a peak of 6.8. With summer temps in the high 70s or 80s, I see 6.4 to 6.6 max, which seems low for a 96.mm.

I'm trying to figure if it's all outside temp related or there actually is an issue. The 96.5mm in summer absolutely feels slower than the 98mm in winter. Honestly, it's felt slower ever since I had the 96.5mm installed.

I have been waiting for temps to drop to see what kind of PSI I will see, but I'm getting antsy.
It will change very slightly like in your example, but there are all sorts of variables involved (IATs, weather, elevation, etc,).
