Just had the K1 done on my cls55. Even better, i got it for half off back when they had their holiday sale back in Dec. Just had time to install everything due to a new baby.

Cory is a real stand-up guy. I fedex'ed my ecu to him and had it back two days later. Had a slight hiccup getting the wires connected (totally my fault ), called him up, and he walked me right through it.

Thanks Cory. You/Kleemann are one class act!

do kleeman mods void warranty?

 

How easy is it to do the ecu upgrade? Also as above, does he K1 void warranty?
