I do believe it is stock diameter, at least it seemed to scale like it was (I didn't measure it). The one I tuned yesterday maxed exactly at redline. Literally hit 5v right as it went into the fuel cut, within one logging sample.
My point with all this is just that I can't see why they'd do that. It greatly limits people's tuning options (only ecutek supports sd, or adjusting maf overrun load calc params).
