End result for both will be similar bhp but higher torque by around 60ftlbs on the GL kit.

How does one know that you are actually getting more power. Motortrend found that the E63S was already generating well over 620hp already. Basically, MB has clearly underrated it at 577hp.
In other words, how does one know that most of the "gain" that you are paying for is not already there for free. Some tuners claim 660hp, but if that is based on dyno testing, then the actual real gain is much smaller than the stated +80-100Hp improvement marketed by tuners.
The reason I ask is that magazines will test and obtain acceleration times (e.g. 0-60MPH) of like 3.2 seconds and tuners (after their tune) will claim massive performance gains, yet there acceleration times are barely different, so the question is for $1,500-$3,500, are gains really being had.
Based on the aftermarket testing I've seen, I'd argue the performance gain is minimal to non-existent. In fact, I have seen some tuners work tested with purported massive power gains and when tested head to head against a stock car, sometimes are actually slower. Happy to keep an open mind, but please show me the data. Before and after tune results...otherwise, it is all snake oil.
BTW...I do not acknowledge drag strip times as evidence based on stickier launch conditions and other mods. Basically, gaining 0.4-0.5 seconds in a quarter mile for like $10k of mods is not very meaningful to me. My expectation is that improved results should be much greater than that for that type of dollar price spent.

Sorry...been there, done that, and highly skeptical of the claim performance gains.

Hey Matt,
How much whp does this add to a stock 2013 E63 with Performance Package? And generally speaking, how is this system making the additional power? Does it dial up boost, or mostly related to removing the torque limiters like the bench flash does? I know most of that answer is probably proprietary, but any insight you can provide would be very helpful.

I don't really understand how some people consider this expensive. Some people shell out nearly $2k for tunes and are constantly worried about their warranties. Now you have the option to remove, without the worry of tracing back to a tune.
I had a software loader for my E63 and GTR and it is priceless.

stock VS tuned M157s, I always see 12-15 cars length and keeps going.
while stock vs stock, almost even.
and this is a test directly after tuning the car
how come there is no difference !
while dyno shows more than 100rwhp gains and 200rwtq gains. and head to head makes it a totally different car in power.
BTW I am not talking about these plug and play tools, but on regular bench tunes (OE Tuning, Renntech, Kleemann, GAD, etc)

My point is magazines don't show those types of gains when testing tuned cars. Call me skeptical.

Hi Guys
We are Rebellion Automotive from the UK across the pond.
We have recently been asked to join MBWorld as a sponsor and are pleased to now be here..
Some of you may know of us with our work on our tuning program for the A45 AMG and CLA45 AMG (if not google is your friend)
The 45AMG project was part of a much larger program of product development over the last 18months that would culminate in a new range of plug and play ECU solutions for Mercedes and other European highend vehicles.
The range of products is named iTuning and relates to our additional ECU and multichannel monitoring and processing system that can be installed and removed as required on your vehicle. The system retains all factory protections and monitoring within the OEM ECU but allows gains not dissimilar to remapping while maintaing reliability and driveability.
With that said, One of the key projects for us was to tackle the M157 engine and the issues that face many potential customers.....Do I want my ECU drilled or opened? If something goes wrong on the car how easy is it to return to stock? If I sell the vehicle I lose the cost of a remap..
The one thing we are not here to do is compete with the likes of EC or Wiestec when it comes to full on remapping of theses vehicles. We have very close links with both these guys here in the UK and if indeed a customer is prepared to go the whole hog on remapping then that is the route we would go...
What we are here to do is to offer and alternative solution for performance gains on these vehicles and although overall peak gains are less than a full remap, the gains we have seen on theses variants is respectable and very noticeable when driving..
The M157 system has been road tested, dyno tested and track tested at the infamous Goodwood motor circuit here in the UK...
We used a 2013 SL63 Bi-Turbo recently and the car produced a respectable 630bhp and 860Nm (634lbsft) on an independant dyno dynamics dyno.
Normal retail is £999 GBP ($1600 approx) + shipping
We will be interested in working with a couple of forum members here to get some cars running the kit in the states...
