Renntech C55 M113 tune impressions

I just reflashed my newly acquired 2006 C55 with the Renntech ECU module. Truly amazing difference in throttle response and overall power increase. I am impressed with the fact that it is easily reversible when necessary. At $995 it is a little more $ than competitors but worth it IMHO. Kudos to Renntech for a quality product.

I did not...everything noted is purely subjective.
