Value your opinions on various tunes
I had posted this in the "Performance & Tuning" section the other day, but haven't had any intel as yet (so I apologize for re-posting in this forum). I purchased a "new to me" 2018 AMG C63 (coupe) and looking to hear about some real world feedback on tunes you have in/on your cars. I've researched the various forum postings but want to know what you think about your tune. What tune did you purchase, ease of install, customer service, cost, problems, performance, updates available, ease of switching between stock/performance mode, piggyback vs ECU update, pros and cons, etc. These are the companies that I've heard about or reached out to (and I know that there are others out there):Need to learn about this so that I can make an informed decision.
Thanks,

Renntech and Eurocharged have the best warranties.
LabWorx and AMR seem to have the most power.
I would really do my research before I picked the other's listed.

I like that that they do not jack up the boost really high in low rpm range like a lot of other tuners out there.
Their tune seems to favor more of linear power delivery.

According to Dragy, this make my GLC the 25th fastest CLC in the world and EC has a great warranty and are fast and efficient on their process and easy to get a hold of at all times.
The tune is supposed to be all mid and high HP gains, if it was more low end I would just spin the tires all day
Def seems to pull more and it doesnt stop. I went up to 135 on PCH by my house before or I got out of the throttle, but it would have kept going......
My first impressions are: the low rpm character has changed ( not as rowdy, most likely from torque management) and and I can hear the turbos now in the mid and upper rpm range ( have never heard the turbos before).
I feel like I got exactly what I was looking for. I was looking for more performance in the mid to upper rpm range.
