Some tuning questions

Just got my GLC 63S this week and sadly just 180 miles on it. After the 1000 mile break in wanted to do some tuning. I've read here about Eurocharged, Renntech and Kleimann was curious if tuned owners would share there experience here.

Also has anyone done the C2 tune? The dealer here in Tampa said they would warranty it only if I brought it to them. It's $2800 to do it and they want it for the day. I'm thinking if they are willing to warranty it might be worth it. I think on this car that's my biggest concern is the warranty I don't want something to break and then MB decided to data log it and denies a claim. Do any of them offer any kind of warranty or any dealers doing certain tunes with warranty? I certainly don't mind paying a few bucks extra if I can get a warranty along with it. I can't imagine a blown motor or transmission repair bill would be fun to have.

For the guys with tunes anyone had it long term? Any issues? Would hate to tune it, do a launch and have it hook and drop the transmission out the bottom. From what I've been able to research these AMG motors are pretty stout. Only heard of one transmission failure so far on the 9 speed due to a tune but the word is he didn't wait the break in but they still covered it. Normally I'm a Mustang guy (I have a Bullitt) and the Ford dealers are usually really cool and normally tunes don't blow the motor up if you get someone reputable. Considering the thousands out there that are tuned they are pretty safe, just not sure about the AMG.

Thanks in advance...

For the eurocharged tune: We have a handheld that allows you to flash it from home. It also stores the stock file to flash whenever you want (dealer visits). The tune picks up some crazy hp. It’s on sale now so just message me if interested! We also have a motor protection warranty on our tuning!
