I just purchased a CLS63 and there is a myriad of tunes out there.. My question is which one has been reviewed and voted the best? I see the Alpha tune promising 700hp 830tq with just an ECU tune.. I see renntech needing to add upgraded turbo's for those same numbers. Can anyone attest to which tune I should go for? A lot of research turns up nothing from actual consumers. Just companies boasting their numbers. Any REAL feedback on which tune to go for? Thanks in advance guys!

 

bump!

 

Hi, this has been discussed before, here's the search results, first link there is a good one

 

Thanks peter, definitely helps!

 

No prob and congrats and welcome --- very sweet ride you have there ... Renntech is the most popular and you can't go wrong with them

 

Congrats on the purchase! Love the CLS.

I'm biased but you should give Renntech a call. Although Renntech claims less hp/tq, it performs equally if not better tune vs tune compared to other tuners. Under promise over deliver

Either way, best of luck to you finding the right tune!

 

I have noticed AMR Performance killing the Mercedes game lately. I just joined the forum since my recent purchase of the C43 AMG and AMR is making more gains than anyone and has record track times with my vehicle. My brother on the other hand has a CLS63 and looked into AMR also. For this platform they advertise a 120hp and 160tq gain above stock with stage 1. I personally find this impressive and would like to recommend checking them out!
