Why did you choose Renntech over other tune?
I don't plan to track my car, and mine is a daily driver, still, I'm thinking about a tune.
Why did you choose a Renntech tune? For those of you who got a tune, but not from Renntech, why didn't you choose Renntech's tune?
For you guys driving a rwd E63 AMG with the Renntech tune, I'd appreciate input as to how the car handles with full throttle from a dead stop?
Seems like the torque is going to cause tires to lose traction and cause a whole lots of spinning, smoke and rapid tire wear?
On another thread, it was commented that the plugs foul and require changing every 10,000 miles. Are you also changing transmission and differential fluids more often?
Renntech seems to have the most aggressive tune. They say they stand behind their tune. However, they don't warranty parts, nor will intercede if the dealer claims the tune cause parts to fail. Their statements seem just that, statements without substance.
There was mention of the aggressive approach Audi has taken to identify flashed cars as TD1, meaning that you are likely SOL if there is a engine or transmission problem.
I believe MB also records which cars have had a tune and takes a similar approach as Audi does.
My underlying question is will I lose warranty coverage for the engine and drive train?

I got my Renntech ECU and 200 cell cats because of the name. If you do get an ECU tune, change the spark plugs ( I got Renntech/NGK ). The tune I got is a blast. Not too many car can touch you on the road. I don't track and it's a daily driver.
As for warrant, it is my understand some Mercedes dealer sell the AMG with the Renntech tune so ?

My dealer has also sold MB vehicles with the Renntech tune already applied. The warranty issue with Renntech & MB is definitely muddy water.

Is your stage 2 tune meant to be used with your downpipes?
I've seen the stuff that Weistec is putting out, but I'm a lil concerned about local support in the event of something not being quite right. Eurocharged is local & my MB dealership is an authorized Renntech dealer. This is my 1st Benz so I'm doing my best to be as careful as possible.
I'm like you. I just want to unleash the power that this engine has & it's my daily driver. I work nights from time to time so I can really get in some "spirited" driving headed home. Plus I'd like to dust the occasional fool that wants to test me. Lol. But I'd probably never track this car.

Local is the key to me personally. Can't beat someone local you can simply stop by to check out the car should the need arise.

If your looking to unleash the beast, tune it. You and your car would thank you for it. Have you seen a Porsche 911 Turbo owner's face when you pass them on the freeway? I have and it's really great.

i was worried about local support too! (i am pittsburgh, they are in CA) but they take great care of you! Had a problem in the beginning, they took the ecu back no charge for shipping and fixed everything at no cost! They have an awesome support system and never abandon customers!! They are a very reputable company and i love their products! But whoever you tune with you will love, it truly wakes up your beast!

Mercedes can and has refused to provide warranty coverage for aftermarket mods installed by dealers. It does not always happen but it can. I have a Renntech tune and mufflers from an MB dealer. But if the engine were to blow up and MB corporate people came to the dealer to inspect the engine/ECU before deciding to replace the engine who knows what would happen.
I might of missed it, but I have not read on this forum that a tuned AMG had its warrantee voided???

There is a pretty good thread on the private lounge that talks about the warranty etc, and what AMG says on the matter

Like EC said, this has been answered on the Private lounge forums. A master tech from MB said that there should not be any alliance or deal that dealers have with a tune compnay. MB does not warrant this or approve of it, no matter what the dealer says. You mod at your own risk.

I had AMS tune my car, very happy with it and the guys from AMS. I chose them because I felt they have the most experience (of the tuners working on AMG's) with high horsepower forced induction engines. Not saying the most experience with Mercedes and AMG but forced induction engines in general, and making them live at extreme power levels. Even as a daily driver the torque gains are great and make the car a totally different animal. I did swap plugs, same as RennTech sells but for 1/3 the cost off Amazon and have 17k miles now no issues.
HTH and good luck with the tune, you won't regret it

With respect to the tune itself I've had zero issues. No check engine lights, no broken parts no problems at all. Similarly the sport mufflers are wonderful, produce great sound and I am quite happy with them. Would readily purchase another Renntech product.
In terms of performance, the car is scary fast. At slipstreams roll races At Pocono international Speedway my car beat every single BMW M car that it faced and it faced many. And it beat the fastest Audi RS7 APR tunedcar in the country. And that is with stock cats and down pipes and turbos.
But it has not had a match against a similarly tuned AMS E63 S. TTA850's AMS tuned E63 S and mine will go head to head at the Atco private track rental on Oct 7. That will be a great comparo as the cars are about identically modded (both have tune, stock cats and stock DPs. His has straight pipes after the cats and mine has Renntech sport mufflers. His has the carbon ceramics and mine has the heavier stock brakes. He has the heavier factory cast wheels and mine has lighter HRE 3 piece forged rims.
I hope someone is going to take some killer videos.

My reason for choosing Renntech was similar. They have the most experience tuning AMG's. They also have the deepest and the closest relationship with AMG. The owner was a former AMG engineer in Affalterbach for many years. Mercedes still calls upon him all the time to help them with concept cars. Renntech built the DJ van that won the awards at last year's SEMA.
