Re: crossfire performance chip
No such thing as a "performance chip". A rewrite of the ECU is the only viable way to tune a Mercedes engine for better performance. Most of us use the Eurocharged tune which has been extremely well tested and worth the price.
Inmotion is another chip tuner who claims a 20+HP increase with their tunes.
