2) Are Active Autowerkes and Turner Motorsport are same product? Same housing? Looking at the installation instructions, they display the same images and they even show a (black) ECU with the same serial number. One is $500 more.

Hmmmm, you might be right on the Active/Turner products. The literature shows the two products are the same – with one costing $500 more. Never noticed this before.

As for the table, you show ESS S55 gaining 550HP/560Tq – not sure that is accurate but perhaps Roman can confirm. Feel free to use this info to update your blank cells.

ESS - “Stage 1 is designed for pump fuel and adds + 60-70 CHP / 60-70 TQ over stock depending on fuel quality. Testing was done on a 100% stock M4 running 91 octane fuel.”
