Same story for DINAN, they have a chart with the deltas.

I would take the advertised gains with a grain of salt. Independent dynos have been conducted on some of them in the sheet.

We just completed testing of the E-Tronic in all modes, look for a separate thread this week showing data/dynos.

Also: ESS E-Tronic allows diagnostic scanning while connected (no OBD2 port lockout).
