2012 E550 with RENNtech ECU
2012 E550 ECU Tune

Hey everyone,

I know the new twin turbo motor has left a lot of HP on the table, and I've been considering a tune. There are a couple companies that offer tunes, obviously RennTech (530 HP & 606 torque) for $2700, and EuroCharged (483HP & 533 torque) for $1550. I want to hear from folks who have experience with any tunes, I'm fearful of the RennTech tune blowing the trans as that's a lot of power..

I'm located outside NYC, anyone know of any shops in the NY area that tune MB's??

Appreciate the feedback.

Porsche 911 Turbo S 2014! E63S 14, Audi S8 13, CLS63 12, E550 12, C63 09, all tuned
I did a Renntech tune to my E550 4 matic bi turbo. No problems, just stealthy fast now. Love it. Put real AMG 255/285 18 wheel on it too. Faster then the 63 NA.

Any pictures of your new 18" AMG wheels?

The 255/285 x 18 came from my 2010 E63. Stock Amg for that year.
If you want pics, I guess I could take some. I just wish they could make this MB

Thanks, only if you have time? I think I saw one yesterday, a very nice five-spoke AMG 18 inch.

I'm debating either the above, or just factory size 245s Michelin Pilot Super Sports.
