Superchips, Powerchips or equivalent

[whestworld]

Has anybody got any experience of an aftermarket ECU chip and are there any that can be recommended for a C43

Sanspeed in Bexleyheath do bespoke chips as well as Superchips and they have a rolling road. I chipped my last w202 with them and was very pleased. HTH

No direct experience but I would go with one of the well known, large and experienced outfits. Superchips are a bit too "off the shelf" for me. Go somewhere they will map your car, not apply one they created on someone elses car.
