Renntech ECU Upgrade E550

Getting close to pulling the trigger on a Renntech ECU upgrade for E550. Has anyone had this done and if so were you satisfied with the results?

How much? There have been no previous posts regarding this so I'm interested. I'm going to have my ECU reflashed by Powerchips next month. I think they are a lot cheaper than Renntech and you get the same result +/- 25 hp and tq. Right now I can't let the car go because of this lousey Mid-Atalntic weather, ie., I need the 4Matic.

Call or PM Jeremy at OE Tuning. He's a sponsor on here, and is largely regarded as one of the best tuners around.

sales@OETUNING is his name on here.

Same, or more gains as RENNtech, for a much cheaper price.

I have attached dynographs from recent (last 2 months) dyno tuning of a GL550 and a S550. The GL550 is measuring Hp & Tq across all 4 wheels, and the S550 is measured to the rear wheels. Consistant gains have been seen across the entire rpm band regardless of 550 chassis. Drivability and performance is is greatly improved. The price is $795.00 for the ecu tune.
Please PM or email sales@oetuning.com for more details.

I believe the list is $1490 however I called them and they were willing to discount it just by me asking. I haven't purchased it yet however and did look into Powerchips and they reportedly will get you a bit more tq. I also have the 4matic as it comes in handy in the Midwest.

$795 for a 550 tune is tough to beat.
