Hi guys,

Anybody done this tune? Have any feedback on it? Im planning to get it on my C63s. Let me know if its worth it.

i have it and LOVE it !!

Thanks,

Should i get it? It's a minimum of 550 HP for the C63s. From the Dyno it seems the car is quick till 5.5 RPM and then dies out. I kind of like that as i don't floor the pedal!!!!

Cheers

Well end the end, its upto you.. I love mine, and RennTech is awesome with support etc.. (not that you really need it, as the upload is simple, and even to put back in stock for taking to dealership etc is simple (2 - 5 min) just flip switch on plugin, and plug into OBD port. (read instructions carefully, as you have to put ignition to certain point, and you need to make sure your battery wont die, or interrupt the process)

Either way, I am sure you will love the results.. it wakes the car up like...

cheers
