Old man wagon ... Renntech or Weistec?
Decided to switch up my dd from a 17 RR Sport SVR to a E63S Wagon ... it should be here within a week.

It's already sort of a sleeper but I'm thinking of upping the power to ludicrous mode with a tune.

If I understand correctly the best two tunes available are from weistec and renntech.

I've never tuned an MB before so I'm wondering if those of you that have can share your experiences and thoughts in regards to which one you would recommend.

Thanks.

Im leaning towards Renntech due to their proximity to me. Aside from that I think they're both putting out similar results.

I have just received my tune from Renntech, it was not cheap in comparison to other tunes available in the market place but I decided to go with it mainly because of its rich history behind tuning Mercedes cars. I wanted usable and safe hp increase over stock and peace of mind so don’t have to worry about running lean.

Is running lean a known issue with Weistec?

I don’t know about weistec and I wasn’t implying their tune would run lean, just saying I feel more confident using renntech.

I was emailing with John Salami there. At least I think that was his name. He was very attentive and knowledgeable.
